Energy or Destruction?: The Hiroshima Atomic Bomb
The Hiroshima Atomic Bomb seems to be commonly used when describing the amount of energy necessary to cause a particular level of destruction. I.e. equating the energy expelled by a natural disaster to N number of Hiroshima Atomic blasts... Morbid?


 * be bold. that's official wp policy. Rhialto 06:36, 2 July 2007 (UTC)


 * At the risk of sounding foolish, I'm afraid I don't understand what you mean :-(


 * I meant, go ahead and add it to the article. :-) Rhialto 15:30, 2 July 2007 (UTC)

Time: galactic year
This sections assumes 'GY' to be the correct abbreviation for galactic year, even though the main article 'galactic year' that it links to has no such justification. By standard metric notation, GY would seem to indicate 'gigayear' (G being the accepted metric symbol for the giga- prefix). It could be argued that the correct unit for 1 billion years is the Giga-annum, however this section utilizes the notation MY as a symbol for megayears, making the use of GY for galactic year internally inconsistent. I am not familiar with the unit and leave correction up to the community. Blackicehorizon 19:59, 18 April 2007 (UTC)

Isn't the SI or metric unit of time defined by seconds and not by any other measure? If so, wouldn't GigaYear be mixing an SI prefix with a non SI measurement making it invalid anyway? Therefore, the abbreviation GY for Galactic Year is fine? By the way, I believe a Galactic Year is equivlant to a Cosmic Year. So, GY=CY? But there is no capital C as an SI prefix, I think. Lawrenceallie (talk) 16:51, 1 January 2008 (UTC)


 * Some sources use "cosmic year" to refer to the entire history of the universe as if compressed into one year. On that kind of scale, human civilization would be a fraction of a second old, and our solar system about three months old. "galactic year" is unambiguous in referring to one rotation of the Milky Way galaxy.


 * As for mixing SI abbreviations and non-SI units, this is quite common and standard practice. Just because a given abbreviation is not SI-compatible, it doesn't mean that it doesn't follow a standard, somewhere. Kilofeet is (or used to be anyway, maybe still) quite a common unit used by radar technologists, and none in that industry should be confused by seeing "kft" to refer to that, although it is quite definitely not SI-compatible. Given that this article is about unusual units, it should not be at all unusual to see, well, unusual abbreviations.


 * According to nist, the year is not SI-compatible, although minute and hour are. As such, it has no official SI abbreviation, although yr, y, and a (for annum, year in Latin) have been seen used for a year.


 * Rhialto (talk) 20:44, 1 January 2008 (UTC)


 * When I search Wikipedia for "cosmic year" it brings me to the galactic year page. If there is an alternate description to cosmic year, should that be placed on a page citing those sources? I am not clear on those rules. Lawrenceallie (talk) 00:37, 4 January 2008 (UTC)


 * Really? WP's article on cosmic year is a disambiguation page which cites four different definitions for the term. Rhialto (talk) 08:08, 4 January 2008 (UTC)

Snail's Pace
Anyone have a cite for people using this as a unit of measurement? "A snail's pace is 5 furlong per fortnight" is not the same thing as "A healthy adult wildebeest can run at five billion snail paces". I suggest that this entry be removed. Rhialto 14:28, 11 October 2006 (UTC)

Since there were no objections, I removed teh section. It properly belonged in an article about snails, not units of measurement. Rhialto 21:32, 11 October 2006 (UTC)

Hubble
I have found a reference to the hubble as 10^9 light years, in the Rowlett's site. Does anyone have an alternate cite for this unit? Rhialto 14:28, 11 October 2006 (UTC)

Use of 'pint' for money in UK
I once estimated the repair cost of the microphone cable in a pub (the sound was a bit of a problem one quiz night), to the landlord, at 'a gallon'. Worthy of note in the 'pint' paragraph?

EmleyMoor 10:31, 13 October 2006 (UTC)

probably not, unless you got quoted in a magazine or newspaper saying that. Rhialto 11:08, 19 October 2006 (UTC)

nanocentury
I corrected the obvious error of 10^7 being really 10^9, and corrected the fraction to be rounded rather than truncated. That may not be in the quote, but the link is dead, and now what is on the page is more correct. First time I've done this, glad to find out what is not fully up to expected norms. Went and got a login after making this edit. (anonymous post)

Actually, I just did the maths, and the correct exponent is 10^7. Rhialto 11:10, 19 October 2006 (UTC)

Hitler
There seems to be a misconception that this page is a list of every fictional unit that has ever appeared in a novel, short story, or web comic. It isn't. This page is for units that have seen general usage in the real world. usage within the pages of a single web comic fail that criteria, although it might be worth noting in an article on teh fictional world of that specific webcomic.

According to WP:V, "As a rule of thumb, sources of dubious reliability should only be used in articles about themselves." and "Anyone can create a website or pay to have a book published, and then claim to be an expert in a certain field. For that reason, self-published books, personal websites, and blogs are largely not acceptable as sources." Also, in Notability, "a topic must be notable enough that it will be described by multiple independent reliable sources."

A weblog is a source of dubious reliability as noted in that policy page, and as such that blog should only be used as a source for articles about the blog itself.

In any case, the source still does not claim the unit sees any usage outside the fictional universe of that webcomic, and the wording in fact implies that the unit does not exist outside said fictional universe. Rhialto 05:58, 21 October 2006 (UTC)

Millirubbia
The article does not say exactly how a Rubbia is calculated. Even the "Helen" gives a method of calcution. This is especially troublesome, since speaking rate can easily measured (i.e. words per minute, syllables per minute, etc.). I feel the definition should be update or removed


 * Agreed. I moved it to Talk:List_of_strange_units_of_measurement/Candidates. Maybe someone can provide a usable cite for it. Rhialto 04:40, 6 November 2006 (UTC)

Cunt hair
I inserted this, and intend to copy some of the discussion over here from Talk:Cunt. I won't reinsert it again unless there is some kind of consensus here, but I have some lingering worries that its removal may be influenced by prudery. As I said in an edit summary, it is as real a unit as any on the page, very common in the military, and wikipedia is not censored. I really don't want to seem like I'm making a WP:POINT here, but if the cunt hair fails to qualify for the article, so would an awful lot of the material presently here. --Guinnog 08:35, 9 November 2006 (UTC)

Unit of Measure (copied from Talk:Cunt)
There seems to be some disagreement on this topic in the editing, so I thought I'd bring it to the Talkpage. I've heard variations on "thin as a cunt hair" and "move it over just a cunt hair" in almost every region of the U.S. While it certainly enjoys popular usage, you can't reasonably expect to find it in a technical dictionary. A ref from a dictionary of slang would seem to be appropriate under the circumstances; that's what the usage is. --Doc Tropics Message in a bottle 04:53, 9 November 2006 (UTC)


 * This debate seems to have moved here from [strange units of measurement]. One issue is that without a valid cite, it looks like gratuituous profanity. Nothing wrong with including swear words where appropriate to an article, but equally where there is no valid cite, it gives the appearance of profanity for the sake of profanity, not to mention original research.


 * The cite that is in there now a dictionary of playground slang, and as such has extremely dubious validity (I'd say none) for any attempt to show usage by aircraft mechanics, enginners, or cooks.


 * Urbandictionary.com was also given as a cite. I removed that as it is not a reliable source according to wikipedia standards.


 * I realise this is an informal phrase and as such cites are hard to obtain. However, lack of cites is by wikiepdia standards, a reason for removing the item entirely, not a reason for leaving the item in uncited. Extraordinary claims require extraordinary evidence.


 * Finally, (relevant to strange units of measurement, but not this article) I have serious issues about including the hair's breadth section at all. As popularly used, it is an expression used to denote a very small distance, and not a true unit. The litmus test for this distinction is whether or not it would be natural to refer to "five hairs' breadth". It should be possible to add a number to the unit and still make sense as natural speech for it to be a unit of measurement. Shedload, bee's dick and others have already been removed from that article for failing this criterion. Items that fail this are more properly figures of speech to denote small or large (depending on expression) quantities, and not true units of measurement.


 * Rhialto 05:04, 9 November 2006 (UTC)


 * As much as I found the original reference amusing, your eminently well-reasoned discourse compels me to agree with you on every point. In truth, I've never heard it used as an actual technical term, just a colloquialism. Further, there's no question that unsourced (or improperly sourced) material needs to be weeded out. I wasn't involved in the actual editing, I just didn't want to see this article turn up in WP:LAME :) --Doc Tropics Message in a bottle 08:05, 9 November 2006 (UTC)

(text copied from talk:cunt ends here)

Most of my reasons for removing it are outlined on the talk page of the cunt article. I wasn't motivated specifically by prudery. It was perfectly valid to remove it as an unsourced statement anyway. To be honest, I feel that not only the specific line about cunt hair, but the entire hair's breadth section, should be removed form this article, as a hair's breadth is not used as a unit of measurement. The litmus test for this is whether people commonly (in as much as the unit in question is commnly used anyway) say "five (unit)s". I have not come across any source which suggests that people do this for hair's breadth.

As for the "awful lot of other material presented here" which supposedly fails to qualify for this article, I agree with you totally. I am slowly working through this article in an attempt to clean it up. It might be worth creating a page under this talk to archive items that are definitively rejected from this page, unless a page is made for expressions such as these. Rhialto 08:49, 9 November 2006 (UTC)


 * I am glad we seem to be in some sort of agreement then. Should we though, first establish a consensus that a "unit" does not qualify for inclusion here unless it is capable of being used in the way you describe, a principle I think I could live with, but which would decimate the article somewhat from its present state? --Guinnog 08:54, 9 November 2006 (UTC)


 * As one of the people who deleted it, I can tell you my motivation was not through prudery. I use the word often and have been the subject of it more than once :) I added Poofteenth and Bee's Dick to this article some time ago but they were removed because they were considered to be just examples of slang and not really measurements at all. It's just something humorous we say when we mean a "little bit" and is not a finite measurement. I reluctantly accepted the argument and didn't pursue it. I think that cunt hair falls into the same category and is not really an example of what this article is about. I also agree that many of the items added to this page in the last year or so don't really belong here. Maybe there needs to be an article for humorous and fictional units of measurement. SilentC 21:39, 9 November 2006 (UTC)

RFC - Criteria for inclusion
The criteria I have been using so far is as follows:


 * Units created for their humour value go in humorous units, unless they have since become significantly mainstream. So far, the only example of that is the Big mac index.
 * Units must naturally be usable in conjunction with any number to qualify as a unit of measurement. Only such measurement units should be included on this page. I have so far held off from serious editing on this point because I wasn't sure about consensus.
 * In considering the above point, it should be bourne in mind that the usual correct usage of the unit doesn't always imply "(number) (unit)". The "nines" unit is one such example. however, it should be possible to include a number somewhere in the usual expression.
 * It should also be bourne in mind that some set phrases for non-measures do include a number, but can be seen as set phrases and not true measures by the fact that they do not get used with numbers other that the limited samples of their set phrase.

Currently, we have a talk subpage for candidates; units which are identified as needing cites. I suggest we also add a subpage noting units that are definitely considered not suitable, to save ourselves arguing the same topic every time a new editor discovers this page. Thoughts? Rhialto 09:25, 9 November 2006 (UTC)


 * My original understanding of this page (once the poofteenth debate was over) is that units included here are sourced from some technical publication, not just amusing things that people say. For example, the Sydharb was originally used as a joke at some presentation in Sydney regarding water, but later it actually appeared in a scientific journal and is now in legitimate use in that field. I'd have thought that this is more in line with the intent of the article, than just satisfying the criteria that it can feasibly be used as a unit of measurement. So I would suggest that in addition to your criteria, there be some formal recognition of the term by the community that uses it. That might be hard to establish, but without this test, anyone can add any amusing unit that they come up with at work. SilentC 21:46, 9 November 2006 (UTC)


 * I think the general wikipedia requirement for citations would prevent that from happening. Wikipedia is not for thinsg you made up, and wikipedia requires citations. These two criteria should prevent random cool ideas from creeeping in, if we enforce them properly. Essentially, it should be usable as a measurement, and there must be cites from a reliable source. That cite doesn't necessarily have to be directly from a community that uses it (any reliable source will do), but where a cite mentions a specific community, the article must obviously agree with the cite. Intentionally amusing units people say, but which are cited, belong in humorous units, not here. Uncited items don't belong in wikipedia at all. Rhialto 21:58, 9 November 2006 (UTC)


 * OK, well let's look at an example: The Happy. I have watched an episode or two of this show. Dave Gorman is a comedian and his concept of 'The Happy' is a piece of comedy. It's totally inappropiate as a measurement because it's definition is subjective. If I give you a pound coin, how happy it makes you is dependent upon how many pounds you already have. A pound coin is of no use to me whatsoever, because it is not legal tender in Australia and I would probably lose most of it's value in exchange fees. Obviously it's not intended to stand up to scientific scrutiny any more than the entire concept of his show is. He would argue that is does, but that's part of the joke. Yet, it's possible to say (as he does on the show) that my happiness has increased by 2 happies. It is cited, as it appears in his show, which you can get on DVD. So does it meet the criteria for inclusion on this page? SilentC 22:25, 9 November 2006 (UTC)


 * No, it is clearly intended to be a humorous unit, and so belongs to in the list of humorous units, not here. I'm going to hold off any major edits until we have some kind of consensus on this rfc though. In comparison, NASA's garn is probably equally as subjective in measurement, but no suggestion (none citeable that I've come across anyway) that it is intended as a piece of humour, so it gets to stay. Rhialto 23:00, 9 November 2006 (UTC)


 * I think it is fair to say that if a unit first appears in an entertainment programme or web comic, and has not reached mainstream usage within its specialised fucntion (no known examples), that unit should go in humorous. Rhialto 23:54, 9 November 2006 (UTC)


 * Nice to meet you two. I think we can do business, improve this article and at least two others. Thanks for your thoughtful comments. Glad my unworthy suspicions of prudery have proved to be unfounded. More tomorrow when I've had some rest. Best wishes to you from Scotland. --Guinnog 00:32, 10 November 2006 (UTC)


 * Just to add, I don't think there should be any requirement that a unit should be objectively measurable by mechanical means. If this page gets sufficiently large, it may be worth splitting them off into another page, or into their own section within this article (may do that as part of the general cleanup). But just because the definition and measurement is subjective, that doesn't mean it isn't a unit of measurement. Its certainly true that such a unit isn't particularly scientific, but this article isn't specifically about scientific units of measurement, I think. Rhialto 00:51, 10 November 2006 (UTC)


 * How does that sit with the opening paragraph: "Strange and whimsical units are sometimes used by scientists, especially physicists and mathematicians, and other technically-minded people such as engineers and programmers, as bits of dry humor combined with putative practical convenience." That says to me that the units listed here should be practical as well as strange and/or whimsical. Maybe it's this paragraph that needs to change? SilentC 01:52, 10 November 2006 (UTC)


 * The problem there is that if we specifically exclude units that cannot be objectively measured, then we muct exclude the scoville heat unit, used to measure intensity of flavour (specifically pepper) concentration. As defined, it cannot be measured objectively, but is used purely in scientific and non-humorous contexts. Besides, I would argue that a unit can be practical without necessarily being measurable by objective means. Rhialto 02:53, 10 November 2006 (UTC)


 * OK, you realise I'm just playing devil's advocate. I'm open to anything really. That said, although it is somewhat subjective, the use of a panel of 5 tasters does lend the scoville heat unit a bit of scientific credibility: it's a statistical sample of the population, albeit a small one. The practicality of a unit would largely depend upon it's scope. If I said that, for all intents and purposes, one metre is roughly half my height, then I would be within a 10% margin of error, which is OK for some situations. However, if my friend who is only 5'4" tall based her 'metre' on the same premise, she would come up short, so to speak. But if she was to adopt her own version of a metre and use it exclusively within her own context, then it is repeatable, measurable and reasonably reliable (as long as she doesn't start wearing high heel shoes) for most purposes. I guess the question I am asking is, does a unit of measurement imply a standard that is understood outside the immediate situation in which it is taken? Is it practical to have a unit that is unreliable or meaningless out of context? It depends on your reason for taking the measurement, but if I asked my friend to build her doorway 2 metres tall, I would have to stoop to walk through it. SilentC 03:33, 10 November 2006 (UTC)


 * Historical weights and measures have a long tradition of being subjective and varying from city to city. That is to say, a "pound" in one city was often heacvier or lighter in a neighbouring city, which historically did cause issues. It wasn't even too rare for human-scale units to be literally measured off against an appropriate body part. I don't hold objectivity in measurement to be a criterion for inclusion. Doing so would shred the corresponding articles on historical units. My criteria are: 1) It must be primarily a unit in an English-speaking country (non-Anglophone based units have their own articles), 2) It must see meaningful use in the present day (i.e. not a primarily historical unit, those have separate articles), 3) It should not have been coined as a humorous unit (these have their own article); an exception is made for humorous units which have since entered use in serious contexts, 4) It must be a unit of measure which is used in conjunction with arbitrary numerical values of a scale appropriate to the items measured (without a number it is more properly a superlative expression or figure of speech). Rhialto 06:21, 13 November 2006 (UTC)


 * One thought I was going to keep until tomorrow, but what the hell: I read New Scientist magazine and it regularly carries semi-humorous pieces on what the popular news media of various countries use to explain things like areas to their readers. Here in the UK, for example, areas are often expressed as multiples of the area of Wales. Would the "Wales" therefore qualify, do you think? There are many, many others, some more commonly used than others, but all (no doubt) verifiable in a reputable source... --Guinnog 00:57, 10 November 2006 (UTC)


 * I have no problem with including "size of wales" style units; indeed, they already are. That style is also used by the CIA factbook, which gets quoted by just about every atlas around. Rhialto 01:41, 10 November 2006 (UTC)
 * For clarity: CIA factbook normally states an area as (e.g.) "2.5 times the size of Washington, DC". This meets the criterion for using a number in conjunction with the unit. Rhialto 22:12, 11 November 2006 (UTC)

Article refactoring?
As part of teh general clean-up, I'd like to refactor the article. I'd suggest sorting units first according to whether it uses a SI or non-conventional scale, then, within the SI section, which scale is used. The headers would be organised as follows:


 * Systematic Sets of units
 * FFF system
 * other systems(none others known for this section)


 * Conventional units
 * Length: unit name
 * Length: unit name
 * Area: unit name
 * Area: unit name
 * Volume: unit name
 * Volume: unit name
 * Mass: unit name
 * Mass: unit name
 * Time: unit name
 * Time: unit name


 * Unconventional units
 * Scale: unit name
 * Scale: unit name
 * Scale: unit name

This would follow the same general organisation seen in other weights and measures themed articles. In addition, it makes it easier for new authors to determine which section a unit should go in, as some of the categories are subjective, and depended on regional usage. This also removes teh special emphasis/ghetto that has been created for only some metric units (metric inch vs obscure metric units, for example). If no one has any objections, I'll begin refactoring some time next week. Rhialto 22:31, 11 November 2006 (UTC)

Foreign Units
As a general policy, I'd like to suggest that any units that are mostly or only used in a foreign country, regardless of the strangeness of that unit, should be moved to an appropriate article that deals with the weights and measures of that country. This is because, by virtue of their being foreign, all of them would by definition be strange to the usual readership of the English language version of this wiki, and there are far too many to include all of them, and no good reason for only including some of them. If no one has any objections, I will begin moving them out to talk/candidates or the relevant article (if known) some time next week. Rhialto 22:31, 11 November 2006 (UTC)


 * When you say 'foreign country', does that mean if a unit is only used in the US, by virtue of the fact that the US is a 'foreign country' to me, it should be moved to a US weights and measures page? ;) Perhaps you'd better define what you mean by foreign. SilentC 21:53, 12 November 2006 (UTC)


 * Specifically, when I said foreign, I meant any country that does not have English as the dominant language. I guess "foreign" is a poor word for this. "Anglophone", perhaps? Rhialto 01:48, 13 November 2006 (UTC)

Jerk
|Bipm, teh authority on this matter, says, "It is requested that the results of calorimetric experiments be as far as possible expressed in joules". they have a few other cites as well which use "joules". That should firmly establish that English convention is to use -s as a suffix to mark plurals, and that the unit name is in lower case. Please stop reverting this. Rhialto 10:14, 20 November 2006 (UTC)

Refactoring Complete
A few items still need cite tags added, and there are still a few items that need moving or removing from this article. Any item with a cite tag is a candidate for removal if cites are not found. But I now consider this refactoring essentially complete. My only concern is the non-standard units section. It is rather long, but I can't think offhand of a simple, objective, and instantly understandable for new editors, way to split that section. Rhialto 22:48, 20 November 2006 (UTC)


 * I'm a bit confused about why this page has the type of measurement stated in its title, and then again restated in each of its subtitles. Isn't the first enough? Do we really need


 * Area
 * Area: nanoacre
 * Area: football field


 * etc., instead of simply


 * Area
 * Nanoacre
 * Football field


 * and so on? I changed it to the latter in the case of Length before realizing it was a style across the board. I suppose someone can either change my revision back or change the other sections to match, but I really don't understand why each title is restated in each of its subtitles. -BlackTerror 19:58, 14 April 2007 (UTC)


 * The reasoning was that it isn't always clear from the name of a unit exactly what it measures. That was more for the benefit of those items in the lower section, a catch-all for units that can't be compared to any SI unit. For the SI-convertible units, I'm not all that bnothered either way (but make them consistent). For the others, I regard it as rather essential information. Rhialto 21:50, 14 April 2007 (UTC)


 * All right, I removed the subtitled units from all but the "other" and "unconventional" sections. --BlackTerror 15:03, 23 April 2007 (UTC)

Contradiction with another wiki entry for the Firkin unit
It seems that this entry : http://en.wikipedia.org/wiki/Firkin defines the Firkin as a volume unit. Which one is right ? I can't tell. Maybe some of you can fix this issue. —The preceding unsigned comment was added by 129.175.65.238 (talk • contribs).


 * Traditionally, the firkin was indeed a unit of volume. And within the FFF system, a firkin is a unit of mass. No contradiction here, simply a case of the same word being used for different units. You probably don't want to know how many definitions of the "foot" there are floating around Rhialto 06:55, 5 December 2006 (UTC)

Do we not also have the cubic furlong available in this system?


 * Presumably the unit of volume under this system would indeed be the cubic furlong. I don't know of any practica use for such a unit though, although I'm hard pressed to think of much prtactical use of any unit derived from these. I'm not aware of any citable authority which defined the cubic furlong though (even though the derivation is obvious), so we can't actually include it here without being accused of original research. Rhialto 16:27, 17 June 2007 (UTC)

Firkin is a unit of capacity, being a 'little-quarter'. The unit refers to a barrel-unit (eg beer), and thence, the net weight of what might be in the barrel (ie without the barrel). The DENT dictionary of measurement gives it as a British unit, (furlongs and fortnights are also british), as being 56 lbs. --Wendy.krieger 10:51, 1 October 2007 (UTC)

List of unusual units of measurement
I would propose renaming this page to "List of unusual units of measurement". Yes, some of these are indeed strange, but most of them are clearly defined units based on other well-known units, and are hardly "strange". They're just unfamiliar to most people. "Strange" also has some flavor of POV. I'll give this a week or so, and if no one complains, I'll move it. Denni  talk 02:25, 21 December 2006 (UTC)


 * I can't see any reason not to make the move. Rhialto 04:27, 21 December 2006 (UTC)


 * Seeing no opposition to my proposal, I shall make it so. Thanks for your feedback, Rhialto. You've put a lot of good work into this article! Denni  talk 21:27, 27 December 2006 (UTC)

Cubic Volume: Olympic-sized swimming pool
There is a contradiction here with estimations on other areas of Wikipedia... http://en.wikipedia.org/wiki/Olympic_size_swimming_pool states that the volume of an olympic swimming pool is 2.5 million litres —The preceding unsigned comment was added by TimDavies4 (talk • contribs) 00:52, 11 January 2007 (UTC).

I noticed the same thing. It's easy to calculate with the dimensions given. I updated the article to reflect this. Chroz 02:07, 4 April 2007 (UTC)

There seems to be a problem with the pool/sydharb ratio - surely from 2.5 M to 500 G is a factor of 200 not 200,000 88.97.16.53 (talk) 18:28, 6 August 2009 (UTC)


 * No, that is quite correct. 500 G is indeed 200,000 times greater than 2.5 M. Rhialto (talk) 21:20, 6 August 2009 (UTC)

afd proposal
See [afd]. We passed it this time, but as the comments show, this article does need more cleaning up. Feel free to discuss here. Rhialto 22:34, 25 March 2007 (UTC)

Tokyo Dome
I have removed this entry from the page. As per an earlier discussion regarding the contents of this page, any unit which is essentially used only in non-anglophone contexts is inherently unusual, and to allow one of them would justify allowing all of them in, and there are just too many to include that way. Units sourced from non-anglophone communities should be placed in a page that discusses the units from that country. Rhialto 09:11, 26 March 2007 (UTC)

Friedman Unit
I suspect this more properly belongs over in list of humorous units. The wiki article on the unit notes it as being tongue-in-cheek, which is a convincing reason in itself. I'll leave it here for the now, but if there are no cites to show serious usage soon, I will be moving it. Rhialto 12:12, 5 May 2007 (UTC)

State of Kansas
I removed the following section from the article. A google search revealed no pages that demonstrate Kansas being used as a unit of length, and no weather pages that aren't directly related to maritime usage that use knots as a primary unit for wind speed. Seeing as how this page has been nominated for deletion, and this subheader has been left uncited for a month, we need to be strict in keeping out potentially spurious entries.


 * Meteorologists in the United States use the state of Kansas, which spans 3 degrees of latitude, as a distance scale on weather maps of the contiguous United States. One nautical mile used to be defined as exactly 1 minute of arc along a meridian., and since there are 60 minutes to a degree, it can be seen that Kansas is 180 nautical miles from North to South. Since meteorologists typically measure wind speed in knots (nautical miles per hour) the use of nautical miles in measuring distances is convenient. Also, the lack of a printed distance scale makes room for other keys, such as color codes and date information

Pov in introduction
Could this be anymore subjective and point of view? Strange and whimsical units are sometimes used by scientists, especially physicists and mathematicians, and other technically-minded people such as engineers and programmers, as bits of dry humor combined with putative practical convenience. --Crossmr 04:34, 1 June 2007 (UTC)

Nominees
1). Megatons/Meter This is a neasure of effeciency of nuclear weapons expressed as megatons of explosive yield per meter of weapon length.  (Source Howard Moreland, "The Secret That Exploded" (I think). 2). Scoville Units (Not certian of spelling) A measure of relative hotness of hot peppers.

Basesurge 19:30, 24 August 2007 (UTC)


 * Scovilel units are already in there. As for megatons/metre, if you can find a proepr referenced cite or three, then you are free to add it yourself. Because of the tendency of people to add cool stuff they thought up in an idle halfhour to this page, unreferenced material is quite aggressively removed from this page, in order to prevent it getting nominated for deletion, so multiple cites are pretty much essential here unless the single cite is extremely well-known/respected. Rhialto 20:48, 24 August 2007 (UTC)

3). Human hair / Head of a pin These are commonly used as a comparative reference for small things, e.g. "one-fifth the thickness of a human hair" or "so small you could fit 20 of these on the head of a pin". — DIV (128.250.204.118 06:01, 3 September 2007 (UTC)) References:, , ;  . On reflection, the "human hair" does sound like a unit (cf. 'Cunt hair' discussion above), the "head of a pin" perhaps not. — DIV (128.250.204.118 06:19, 3 September 2007 (UTC))


 * This one has already been rejected after a big discussion. Our standard criteria for units in this article is that the people must regularly (within the context of the unit in question) say "five (units)". For this item, people only use it in a comparative sense to describe a very small distance, and not to actually attempt to measure a specific distance. Rhialto 06:56, 3 September 2007 (UTC)

Non-English speaking countries
The intro says "For units that are primarily used in non-English-speaking countries, please see the article on units specific to that country." But there is no link and no obvious way to get to those lists. I assume such lists exist, else the statement makes no sense. If not, this is not done the right way. Info should only be split off from an article if a sub-article exists. Also, shouldn't the title of this article then be "List of unusual units of measurement in English speaking countries"? A bit long, I must admit, but still. DirkvdM 08:24, 14 September 2007 (UTC)


 * That line was originally included because otherwise, units such as the Japanese shaku and the Maltese qasba would logically be placed in here, making this article ridiculously long. I guess it would be worth including a list of links directly, instead of linking to the official list article (Systems of measurement). Some units, such as the "reindeer piss" have been moved from here to the Finnish units article. Rhialto 08:50, 14 September 2007 (UTC)


 * Those are normal units of measurement. This article is about unusual units of measurement. If the list would become too long, then wouldn't it make more sense to start an article List of unusual units of measurement in non-English speaking countries? Maybe start it at the bottom of this list and then make the separate article when it gets too long. And then when that list becomes too long, specific countries might start splitting off. That is the normal way Wikipedia grows, as I understand it. Anyway, it can't be right to refer to other articles but not provide a link to them. DirkvdM 18:24, 14 September 2007 (UTC)


 * In the previous discussion on this area, it was pointed out that any 'normal' unit originating in a non-anglophone country, within the context of being read in the English version of wikipedia, must inherently be unusual simply by virtue of being foreign.


 * As for the list becoming too long, it already became too long twice before, the first time resulted in the entire article barely surviving a request for deletion, one of the prime criticisms at the time being that it was too broad in scope. opening it up to non-anglophone units restores that threat of the article being deleted.


 * However, I am fully in favour of an equivalent article being started elsewhere within this wiki. I just don't think it should be appended to this article, as otherwise it broadens the scope of this article to a level that threatens its existence. I am going to add the link to that index article for foreign units too. Rhialto 18:50, 14 September 2007 (UTC)


 * Like I said, once this article gets too large, things can be split off (in stead of deleted - I am a fervent anti-deletionist). Starting with the foreign languages section. I just proposed to start it here because there are not enough entries too warrant a separate article (or are there?). Once there are, it can split off.
 * An alternative would be to add those to separate sections in specific country units articles, but there are no such articles. Maybe those should be created, again preferably starting with one overall article List of units of measurement in non-English speaking countries or just Units of measurement in non-English speaking countries and then splitting off when it becomes too large. DirkvdM 07:46, 15 September 2007 (UTC)


 * I don't like deleting stuff either. But because this article has been threatened with deletion in the past before in a formal vote because fo a lack of focus and lack of verifiability, it is extreemly important to be vigilant in removing anything unfocused or uncited.
 * An aditional danger with starting a foreign language section is that the items might not, within the context of the English wikipedia (though not so within the context of that language-specific wikipedia) be sufficiently notable. A reasonable case could be made that such a split-off article for unusual units in non-anglophone countires isn't sufficiently notable, let alone sufficiently focused.
 * It is also my opinion that the language-specific articles on units, for example Finnish units of measurement (which includes the reindeer-piss as a unit of length), do allow for such unusual measurements to be included.
 * Finally, any unit which doesn't have a specific 'list' article can always appear in its own article. This does of course raise an extra issue of notability, but that should not be a problem if the unit in question is well-cited and actually notable enough in its own right. Adding non-notable units to this article simply raises teh danger of the entire list article being deleted. Rhialto 09:37, 15 September 2007 (UTC)

Hoppus Foot
A unit used for raw lumber, corresponding to a cylinder 4 feet in circumference, and one foot or inch long.


 * 'Oxford Dictionary of Weights, Measures and Units" by Donald Fenna (isbn 780198605225) gives thus as 4 foot circumference, and one foot long, while ASA 1375 gives this as 4 feet in circumference, and one foot long.


 * I have seen also this applied to a hoppus board foot (4 feet circumference * 1 inch), this is 4/pi board feet. Wendy.krieger 10:30, 28 September 2007 (UTC)


 * A google-search on 'hoppus foot' brings up many entries, with a hoppus board foot = 1 inch, hoppus foot = 1 ft, and hoppus tun = 50 ft, all of a cylinder 4 feet in circumference. --Wendy.krieger 09:35, 30 September 2007 (UTC)


 * I can't see any reason for you not to add it to the page. Rhialto 09:42, 30 September 2007 (UTC)

Cubic Acres
There are plenty of references in Google for "cubic acre", and where the measure is given size, is translated as 208.3 acre-feet. Watch out for 'cubic acre foot', which is the same as 'acre foot'.

Many science-educated people get confused with the subtle difference between "cubic" (which refers to volume), and cubed (which refers to the third power). So one takes 'cubic acre' as 'acre cubed'. It isn't. In the rough, 'cubic', 'square', and 'linear', apply to the dimensions that a unit might be applied to: volume, area or length. It is quite acceptable to use a unit without this prefix (eg 'yard of soil'), even where the unit is used for a different quantity.

So, there are indeed many references to 'cubic yard', and the meaning is perfectly clear, except for those who make the cubic/cubed confusion. --Wendy.krieger 11:01, 1 October 2007 (UTC)
 * It's worth noting that a cube with each face being one acre in area would have a side length of 208.71 feet (and thus a volume of 208.71 acre-feet). --Random832

I'd like to point out since the acre is NOT a square unit (rather a rectangular one of either 660 x 60 international or U.S. customary (Mendenhall order feet), it is actualy a paradox. 208.3?  That is not what the acre was defined as, and I have to admit, I struggled greatly in school until I learned its actual, historic, non-metric measure; then it made perfect sense.  I get similarly muffed when I see decimal thousandths of an acre as when I see "cunt-hair" in a measurement article.  They're both completely absurd and their authors aught be ashamed of themselves! 74.199.103.79 (talk) 21:22, 16 November 2011 (UTC) (contribs) 20:46, 10 July 2008 (UTC)

Liberalism: The Brennan Scale
I've moved this unit out of the main article, since it is uncited, a quick google search reveals no obvious signs of such usage, and as the alleged unit is named after a real person, it could be construed as a personal attack (wp:bio). Rhialto 06:40, 13 October 2007 (UTC)

Planets
How about Planets as a measure of ecological footprint, as seen at http://news.bbc.co.uk/1/hi/uk/7057346.stm ? It's sort of mentioned in the article for ecological footprint, but as this is becoming increasingly popular in the media, I think it should be added here, and on the disambiguation page for planet. Nick Fel 10:29, 24 October 2007 (UTC)

units in non-anglophone countries
As has been noted in teh opening paragraph for many months,


 * "For units that are primarily used in non-English-speaking countries, please see the article on units specific to that country, links to which can be found in Systems of measurement."

Without this limitation, the scope of the article would be so broad as to make the article impossibly long for any modern web browser to handle the complete article. This doesn't mean that such units have no place within the overall wiki, just not within thsi specific article. Rhialto 18:09, 30 November 2007 (UTC)


 * I can see why you might wish to restrict the scope. My motivation for rewording the introduction was only to *clarify* that scope as I now understand it.  The statement that some units can be found elsewhere does not preclude their presence here, so I made that more explicit. Did I get that wrong? Thunderbird2 18:23, 30 November 2007 (UTC)

Half-a-Heartbeat
I remember many moons ago that a teacher would use the phrase "half-a-heartbeat" when requesting something to get done; for example, "you got half-a-heartbeat to get back to your seat". Would this be an unusual measurement or just a dead metaphor? Lawrenceallie (talk) 00:26, 3 January 2008 (UTC)
 * I'd think it's just a metaphor, unless you can find serious publications which do things in terms of half-a-heartbeats. mattbuck (talk) 02:58, 3 January 2008 (UTC)

An irrelevant joke
It stuck to my mind that a Finnish CGI comedy series about the country's government (yes, really) began its space musical special (yes, really) with a news broadcast about an incoming asteroid roughly the size of Texas. As Finnish viewers live on an entirely different side of the planet than the state, it then immediately clarified that Texas is roughly the size of a large asteroid.

In other news, could someone from a country that uses it add "breadbox" to the article and dig up an instance or two of its use? --Kiz o r  13:09, 12 January 2008 (UTC)

nano-c
In some discussion in our german WP we just came across speed and why the speed of light c is not used as the general reference for all speeds, as it is such a universal constant. When looking deeper into the issue, the "nano-c" might be useful, as it's fairly comparable to the common European speed unit km/h: 100 km/h = 92.6 nano-c, or 1 nano-c = 1.07 km/h. So there's only a 7 % difference between the two. So this could become fairly usable. So this is per assumption a new invention and probably not found in any sources. Or? --PeterFrankfurt (talk) 00:37, 13 February 2008 (UTC)


 * That looks like original thought to me. Rhialto (talk) 07:42, 13 February 2008 (UTC)


 * And you are mixing up quantities and units here. The speed of light is c (italic), not 1 c (roman). Prefixes are only attached to unit symbols. So first you would have to define a unit whose symbol is c, and then take it from there. --DrTorstenHenning (talk) 12:03, 13 February 2008 (UTC)


 * It's even closer to foot/sec. :-)  1 nanocee = .98357 ft/sec Nik42 (talk) 03:58, 14 February 2008 (UTC)

It was just a sudden idea. And the original discussion entry (from someone else) wanted to use c as one of the basic units in a measurement system similar to SI. At first I found that hilarious, but after reasoning, I began to sympathize with the idea. And this is of course the discussion page, not the article, I know that such stuff would need "a bit" more support before full publication. --PeterFrankfurt (talk) 22:54, 13 February 2008 (UTC)


 * An interesting idea. The basic unit of length could be defined as the distance that light travels in one nanosecond.  The second, of course, would be defined the same as it is now.  This would make the basic unit of length be 29.9792458 cm or 11.8028526772 inches, i.e., very close to a foot.  Perhaps, you could even use the name "foot" ("scientific foot" if you need to distinguish from the "traditional foot").  The basic unit of volume would be the cubic "decifoot" or "inch" (26.94 ml or .911 oz).  The basic unit of mass would be equivalent to the weight of one 1 cubic decifoot of water (26.94 g or .95 oz).  Ironically, those units come pretty close the the American system ... :-)
 * By definition, foot/sec would be equivalent to nanocee Nik42 (talk) 03:58, 14 February 2008 (UTC)


 * Such a unit would be, obviously, the light-nanosecond per second. Unfortunately, it's not used anywhere... Wtrmute (talk) 23:01, 21 February 2009 (UTC)


 * For what it's worth, i did this back in 1977. If you set c = 1e9, G=1e-9, you get a foot of 299.792458 mms, and a pound of about 404.454 grams.  The density of 1 g/cc is represented as 1e12 G, where G is the SI value of newton's gravity (eg 66.7428).  You get epsilon and mu as 1e-9 as well.  Twelfty naturally follows Wendy.krieger (talk) 10:31, 1 June 2012 (UTC)


 * Of course the Galactic standard is not tied to parochial units such as the rotation of a particular planet, or the number of appendages of one species; its usual units are n! times Planck units, for some convenient n. ;P —Tamfang (talk) 10:44, 1 June 2012 (UTC)


 * Or base :S Yes, even among english units, you can't expect the hundred to be five score.  It was typically six score for things that had heads (nails, people, sheep).  I'm hardly sure of factorials, either.  I did one once based on the powers of 137.03599961, which has a number of interesting transits in the regular space.  Using a power-based system like this gives one more measures coherent to the system: you can have for example, eight base units.  Wendy.krieger (talk) 08:58, 2 June 2012 (UTC)

iPod nano index
There's a slight problem with this one, so I hope it was just supposed to be a spoof on the Big Mac index (which itself would be subject to similar...) - the company selling the item also has a hand in setting the price, as well as all the other market forces. And with something like the ipod, Apple has a fairly free reign, thanks to their all-conquering marketing blitz (it's not that better rival products don't exist, for a lower price ... just no-one brainwashed by floaty Feist music and wierd imagery into running out and getting a shiny 2Gb mp3 player in a range of colours will have heard or be bothered to learn about them), they can almost name their price, so long as they think it'll still sell in sufficient numbers to comfortably crush the opposition.

Add to that, for the UK, the "transatlantic gadget exchange rate", where things importing from the USA (market - regardless of it being made in china) to the UK seem to be sold at a dollar:pound exchange rate of 1:1, regardless of what the true value is. This has become even more absurd since the dollar has settled at an almost $2.00:£1.00 real rate, and since Apple tried to sell music tracks that were 99c in the states for 99p in Britain, even though it's all going over the internet and there isn't even the excuse of shipping costs (flimsy at best even for the ipods - I know what INDIVIDUAL carriage charges from the orient and the USA are like and have an idea of bulk ones, and they're not on the magnitude of £100 for package the size of a normal paperback book). This traditional, groundless and much lamented price-gouge by major electronics manufacturers must surely skew the result some, even though the country's purchasing power on a range of other more important and, on aggreagate, more economically valuable things (food, fuel.. cars.. labour..) is completely unaffected by these shenanigans. —Preceding unsigned comment added by 82.46.180.56 (talk) 06:12, 25 March 2008 (UTC)

Possible addition: kilobase
The kilobase (abbreviated kb, confusingly) is a common term used in genetics to refer to the length of a gene sequence; it's equivalent to 1000 base pairs. So bacterial plasmids, usually between 4 to 10 thousand base pairs, are 4-10 kb. This is for both size and distance, so one sequence may be 3 kb downstream of another. Larger sequences may be measured in megabases, gigabases, etc. The article on Base pair discusses these units, but perhaps a mention here is warranted as well. 74.236.79.85 (talk) 09:40, 25 March 2008 (UTC)

Outhouse
I'd just like to point out that it isn't obvious nonsense- there is a link on the outhouse (unit) page to a site defining this unit, and the link looks reasonable to me. Loggie (talk) 10:45, 11 May 2008 (UTC)


 * Okay. I'll revert my edit. That reference looks reasonable. I'd seen many references in the past to barns and sheds, but this was the first one to an outhouse. It possible has issues in terms of notability (as it ever actually been cited elsewhere? Is there any other source that notes the existence of the unit, or is it a deliberate bad data he made in his site to spot data miners and detect copyright thieves?) But it would take an unreasonable amount of effort to find more data on whether it should be included. Rhialto (talk) 11:01, 11 May 2008 (UTC)
 * I was able to find other sources for the shed article, but I haven't had any success with the outhouse, but then, I am only looking online as I don't have access to paper sources. So, I can't answer those questions, sorry. Loggie (talk) 11:07, 11 May 2008 (UTC)

Distance as "minutes"
This is hardly a Philippines "phenomenon" or in the US, limited to the "southern region"; nor is it really all that 'unusual'. Throughout the US, when travel is involved, using time instead of distance is quite common -- especially in (but not limited to) cities of all sizes. vmz (talk) 16:44, 5 June 2008 (UTC)

Not only in the US, it's used all around the world. Most train and subway systems give travel times and not distances. Most trails are given in time (like 2.5 hours to the top of the mountain). But in all these cases, it's really a measure of time and not distance, as what is given is the time to get to a point using a certain mode of transport (walking, car, train ...). So it's not an 'unusual unit of measurement' as minutes are a common unit for time. I think this section should be deleted.AtikuX (talk) 09:02, 27 June 2008 (UTC)

Attoparsec
What is the significance of attoparsec/microfortnight? Is it a quotation or meme? If not, why not remove it or use the slightly less obscure picoparsec/fortnight? Also, is it fair to describe this verifiably correct (if useless) statement as a factoid (a spurious — unverified, incorrect, or fabricated — statement)? Certes (talk) 00:59, 29 December 2008 (UTC)


 * If a factoid is always incorrect and/or unverified, how can the attoparsec/microfortnight be spurious, since it is, after all, both correct and verifiable?


 * I agree though, that the entire attoparsec has questionable relevance. It probably has strong currency as an Internet meme, and perhaps someone may think it is viable as a humorous unit, but I haven't seen any evidence that people use attoparsecs for any real-world use, however esoteric. Rhialto (talk) 07:21, 29 December 2008 (UTC)


 * That was my point: attoparsec doesn't fit WP's definition of factoid. I agree that removing the Attoparsec section of the main article was probably the best solution; thank you for being bold. Certes (talk) 15:07, 1 January 2009 (UTC)


 * Undone - it is a unit in common use in some circles. Google it, there are 22000 results for attoparsec. The attoparsec/microfortnight might be a bit much, but don't go destroying things just because you feel like it. Teque5 (talk) 09:08, 6 February 2009 (UTC)

smoot
I recognize the purpose of this article is not to document every unusual unit of measure that ever existed, even though the smoot is well-known and noteworthy enough to merit its own article here. For that reason, I would like to get an opinion before WP:Boldly adding it, looking something like this:

The smoot is a nonstandard unit of length, named after Oliver R. Smoot, equal to Smoot's height (five feet and seven inches, or ~1.70 m). &mdash;GraemeMcRaetalk 03:10, 5 March 2009 (UTC)

KLOC
1 KLOC != 50 days of work: I programmed 7.5 KLOCs in 4 months == 120 days, not 350 although I am programmin (including testing and bugfixing) an average of less than 2 hours per day + I'm programming since less than a year. The IBM software engineers should surely program more than that, even if their programming languages were uglier and their programming interface was really hard to use. Please either remove this subsection or hand out some proof. Additionally, just saying 'lines of code' is quite imprecise: It is actually the lines of SOURCE code. For example, C would compile into more lines. These give a more precise definition of the term, although I don't think C++ is a high level language >_>

SI-compatiblity of the Langley
Listed under Other SI-compatible scales is the langley. It is defined as "one thermochemical calorie per square centimetre". How is this SI-compatible? The calorie is not compatible with the SI therefore neither is the langley. J IM ptalk·cont 14:45, 21 June 2009 (UTC)


 * I'd say it is probably because there is a definable mathematical relationship between all the base units used to define the langley, and all the base units involved in SI. As such, there is a precise mathematical relationship between langleys and the equivalent SI scale (J/m^2). There is no such precise relationship defined, or even definable, for the units in the later section of the article. Rhialto (talk) 15:05, 21 June 2009 (UTC)


 * There is a precise mathematical relationship between the inch an the millimetre. I've always taken SI-compatible to mean something more. How about we broaden it to metric-compatible? J IM ptalk·cont 15:16, 21 June 2009 (UTC)

The firkin of water
The article claims that the firkin of the FFF system is equal to 40.91481 kg. How do we get this?

A firkin is nine imperial gallons, i.e. 9 ×  4.546 09 litres or 40.91481 litres. The kilogram was originally defined as the mass of a litre of water at the temperature at which the density is maximum (~4 °C) at standard atmospheric pressure. Therefore we obtain a density of 1 kg/l for water. Using this we calculate the firkin of water to be 40.91481 kg.

What's wrong with this picture? Why are we basing the definition of the firkin along the lines of the kilogram? Why go with the density which the creators of the metric system felt suitable? Isn't the FFF more akin to the imperial system?

The imperial gallon was originally defined as the volume occupied by ten pounds of water at 62 °F. This gives a density of 10 lb/imp gal from which we calculate the firkin of water to be 90 lb.

Furman/Brad
The Furman section of the article mentions another related unit that is 1/256th of a circle, but says it doesn't have a common name. I've always known this unit as the Brad (binary radian). Wikipedia actually also calls it a Brad on the Angle page, but there is no citation. Perhaps something should be done to reconcile these pages? Searching for "brad" on google didn't give me anything good in the short amount of time I spent on it and I can't spend more time right now. Yanroy (talk) 18:47, 5 August 2009 (UTC)

Sourcing some of these units
Hello,

I took this first to Template talk:Convert, where I am an itinerant when I want to use or correct units of measure (and good work by all the people there), and was advised to talk here, so I will. It is a little off my beaten track but sometimes I stumble on an unusual unit, or more often, on one that makes little sense worldwide (I don't mean Metric/SI but "about twice the size of Rhode Island" and that kind of thing). So I started looking at this series of articles and notice that many units, those that are not simply made-up, could do with better sources.

So here is:


 * "According to official figures provided by the Royal Albert Hall's management the horse's mouth itself { the volume of the auditorium is between 3 and 3.5 million cubic feet, so that's between about 85,000 and 99,000 cubic metres." I appreciate this is a somewhat jocular style,  but so is the whole book as you may imagine from its title. That is secondary source but would reduce to primary source if that information is on the Albert Hall's website or something. But it's a start.

Similarly the milliHelen I think was first noted in a letter to the London Times, I had it in a book entitled "The first cuckoo" which was a collection of notable letters written to the times, some profound and some funny (and some both), but somebody borrowed that and did not return it, but it was coined between 1960 and 1970, ish, about the last quarter of the twentieth century, and in the absence of any other source, if I can find and quote that, it will stand as verifiable, though I am sure someone else will then find an earlier use, which is all to the good.

The thing is, then, to get as many of these units as we can onto a firm footing for WP:V. I hope I helped with one, at least.

Stère
A stère is not the same as a cubic meter. Stère is used for logs, with gaps between the logs. So there is about 0.8 m³ of wood in 1 st. Roymail (talk) 12:28, 30 October 2009 (UTC)

A stere is indeed a cubical metre. It's the firewood, not the volume, that contains the holes. See also, cord = 128 cu ft, and klafter (108 cu ft, in Germany). Next one might be saying that a bushel is not eight gallons, because the fruit and grain has holes in it! Wendy.krieger (talk) 10:37, 16 October 2011 (UTC)

 * Removed soon after here . I agree with the removal. Other then being unsourced, no evidence was provided it's used as a unit of measurement of volume or anything else. Sure it may be used for size comparisons, but that's a different thing. People don't say hail the volume of two golf balls, they say hail the size of a golf ball, the size of a tennis ball....

Whether things like the Albert Hall and football pitches are actually units of measure
Discussion here copied from my talk page, change by the other user resulting in my undoing/reverting just as part of the usual WP:BRD cycle, and I think the D should be here: &mdash;&mdash; Si Trew (talk) 06:37, 22 June 2010 (UTC)

"A unit of measure, a standard, is by definition a comparative measure"

A genuine unit of measure is not comparative at all, it is absolute, whereas what you mean by "a comprative measure" is not a measure at all, it's a comparison. I think you are confusing the unit of measure, with the method of measure. Holding a ruler up to an object is a comparitive method of measurement between the ruler and the object, but it is not the units that are being compared, it's the ruler.

When measuring in inches, for example, one does not say: "This object is equal to an inch in length" (comparitive), one says "This object is one inch long" (absolute). You cannot physically compare the unit of measure to an object because the unit of measure is an abstract concept - you can't see or hold an inch in your hand.

If all comparisons were considered genuine units of measure, then every time two things are compared, a new unit would be created, which is absurb - "My sister's fatter than a bus" does not allow sisterly fatness to be measured in buses, and nor does comparing the number of tyres it takes to fill the MCG automatically make the MCG a unit of measure for volume, especially when the reference article (which may or may not be a one off comparison) does not even state this.

Specifically for the changes I made, the articles cited didn't even claim, nor use them as units of measurement. All cited articles simply made comparisons. If you think they are genunine units of measure, you would need to provide articles that either define them as such, or at least use them as genuine units of measure.

Mr Pillows (talk) 04:06, 22 June 2010 (UTC)


 * First, can I just say I undid your changes as part of the usual WP:BRD cycle, and if you're willing then it's probably best to transfer this discussion to Talk:List of unusual units of measurement.


 * I'll also say thanks for calling them units of measure, not units of measurement. Why people have to go for that longer form all the time baffles me. And also the confusion between measures, and units of measure (for example that people say "20km is a unit of measure", when generally they mean it is a measure).


 * Now, to your point about it being comparative or not. By your own definition you have said that "This object is equal to an inch in length" is equivalent to saying "this object is one inch long". That is, the comparison is there in both cases, just that in the latter case the syntax changes. The comparison remains.


 * In fact an inch (and other units of measure) are physical things. In the case of an inch it is now defined as 0.0254 metres, and the metre is in turn defined as so many wavelengths of the light emission of some isotope of strontium, but until relatively recently there were several "real" metres which could be and were used physically for comparison. The kilogram still is a physical measure; it's not defined in "abstract" physical terms.


 * If the reference article does not make comparison to the Albert Hall, for example, then of course the reference should be removed. Either at that article or this one, I noted down the volume of the Albert Hall and sourced it, but it was not from the BBC. I don't know about the others.


 * I suppose what I am saying is that anything that is used as a comparative measure is by definition a unit of measure; something you disagree with either (or both) because we generally do not measure it directly against the standard (we might measure our recipes on an inaccurate kitchen balance rather than carting our flour off to Sevres to have it compared against the international standard kilogram) or because the syntax of the sentence changes, generally because we are using nouns that are not fungible (there are not three Albert Halls, so we find it odd to say something measures three Albert Halls). The abstraction does fall down a bit in that there are all kinds of measures the Albert Hall might represent (its volume, seating capacity, and so on) but the fact is if we've picked one then it becomes a de facto unit of measure, albeit a rather loose one, since nobody actually seems to know how much volume is enclosed by the Albert Hall with any great accuracy.


 * So what it comes down to is whether an Albert Hall, etc is an unusual unit of measure. I'll make a definition of "unusual unit of measure" so we have something concrete to argue about:


 * An unusual unit of measure is one that is frequently used informally, whose measure is approximately know, but does not fit into a coherent system of units such as US Customary or SI.


 * I imagine we could come up with a better definition than that, because that might include things like parsecs or light-years, astronmomical units and so forth: I would argue these should be listed as "unusual", I imagine others would not; certainly they come under the definition (at least if you accept that the definition implies that something is unusual if it is not a neat multiple or fraction of other units in the system, and even then we should probably restrain the factor or denominator to 1, 2, 5 and 10).


 * So, I am saying that the whole article title may be somewhat misconceived: what does one mean by an "unusual" unit of measure? In the UK, horse races for example are always measured in miles and furlongs, and barrels of real ale in firkins and halves (a pin) and multiples (kilderkin, barrel, hogshead) thereof. But the article lead of FFF system calls them "impractical and outdated units". On the other hand, you are not arguing with the fact they are unusual, but whether they are units of measure at all. I think they are, and that just because the surface syntax changes for some of them (it needn't for things like the milliHelen), that doesn't stop them being a unit of measure. All that remains is to say that "the length of a football pitch", "the size of Wales" is the unit of measure; but we do the same when we say "one pinch of salt" or "two shakes of a lamb's tail", and I don't think one would dispute that we are measuring volume there or time. What would definitely be erroneous is to define "2 volume" or "3 time" as units of measure; but there is no danger of that here.


 * Sorry to make this so long. Best wishes. Si Trew (talk) 04:49, 22 June 2010 (UTC)


 * PS. There are at least two things we should do to the article:
 * Change title from "measurement" to "measure", and similarly throughout the article where appropriate.
 * Change title to remove "list of", as it doesn't seem to me to be a list article in the general Wikipedia sense: it includes more content than is typical in a list article.
 * Si Trew (talk) 04:54, 22 June 2010 (UTC)


 * "In fact an inch (and other units of measure) are physical things. In the case of an inch it is now defined as 0.0254 metres, and the metre is in turn defined as so many wavelengths of the light emission of some isotope of strontium, but until relatively recently there were several "real" metres which could be and were used physically for comparison. The kilogram still is a physical measure; it's not defined in "abstract" physical terms."


 * I don't want to create an argument, so I will not make any further changes to the article, but:


 * 1. A physical thing is something you can see and touch. You cannot see or touch an inch because it is only an abstract concept. You can define the length of an inch using a comparison (eg 1 inch = 2.54 cm, or 1 inch = 1/12 the length of the king's foot, etc) and you can see a comparative object which is the same length as an inch on a ruler (the wood between the 0 and 1" marks), but the inch itself, along with all units of measure, is an abstract concept that has no shape or form.


 * 2. I'm not saying a Royal Albert Hall couldn't be a unit of measurement, I'm simply saying it isn't a unit of measure in the reference shown and I additionally doubt it has ever been used as a unit of measure. The simple solution is to find a proper reference that measures a volume in RAHs - ie "Britain creates 1000 RAHs of landfill in a year". This would need be done in order to meet Verifiability.
 * Mr Pillows (talk) 05:42, 22 June 2010 (UTC)


 * I don't mind having an argument, providing it's good-natured (and I think this is): that's how we get consensus.


 * The use of syntactic forms such as "ten milliHelens" can easily be found. Googling for "ten Albert Halls" (exact search) gives three matches; one of which I believe would be RS but unfortunately neither the cached version of the page is available (a subscription trade magazine); of course by extending the search to other numbers and so on i am sure it would pull up something near, but not exactly what fits your definition. i.e. the point of contention here is the use of "size of", "worth", "length of" and similar qualifiers. Personally I don't see that that disqualifies something as a unit of measure, but you do (I think; I don't want to put words in your mouth).


 * I didn't take "physical thing" as being something you can touch and feel, but something that can be measured, to some known degree of accuracy, by physics, as opposed to being some Platonic ideal. I think that that is common ground, but perhaps not; I think it leads to some odd convolutions, particularly with mass. "Light" in this sense is a physical object (albeit a massless one) but "the speed of light" only a conceptual one, that is, "speed", "volume", "length" et are concepts. In this sense I think you are arguing simply that because "length of", "-worth", and so on are included in the statement, that they discount the thing form being a unit of measure; I disagree because I have a fundamentally different idea of what a unit of measure is, which is "This is one of some quantity, how much is something else a multiple or fraction of that thing?", and whether that requires a certain syntax very much depends on the surface forms we have available in our language's syntax, and does not, in my view, change that it is being used as a unit of measure, i.e the Albert Hall is 1 Albert Hall, a units-worth of Albert Hall.


 * These days the measures of everything except mass are derived from the universal properties of light (its speed and so on), but the kilogram is just defined as "as much mass as a particular lump of stuff at Sevres has", and that lump is certainly a visible, touchable object. Yet we don't say "as much mass as ten International Standard Kilograms held at Sevres", we say, "ten kilograms", though it means the same thing. So I can't see that the particular syntax of the measure changes it from being a comparison with what, by definition, is then a unit of measure.


 * Best wishes, I'll copy this to the Talk page. Si Trew (talk) 06:37, 22 June 2010 (UTC)


 * Ah, I think I can summarise the disagreement thus: if the object does not have an implicit dimensionality, it cannot be a unit of measure. So, the Albert Hall is not a unit of measure, but the seating capacity of the Albert Hall is; similarly not a football pitch but the length or area of a football pitch and so on, whereas "inch", "kilogram" and so on have their dimensions built into their definition.


 * I can see that as good reason why "the Albert Hall" is not a UoM, but I don't think anyone is claiming that: the "volume of the Albert Hall" is. But we don't repeat higher-level titles in lower-level ones, by WP:TITLE, there's nothing special about that, and does not stop it being a unit of measure (or, in the alternate, make it so).

What belongs on this page?
My addition of a paragraph on units of fuel consumption was deleted by User:Rhialto, with the comment “This is a ratio of two unit; the base units themselves are extremely ordinary.” True, but something similar can be said for many of the other entries on the page (“SI-imperial hybrids”, light-nanosecond...).

Actually, the page seems a mish-mash of units that are considered remarkable in any fashion. The lead itself seems at rather hesitant as to what the page is about (“This definition is deliberately not exact”).

Maybe the entry on fuel consumption does not belong here. I feel it does belong somewhere. In any case, something should be done to fix the mess the page now represents; perhaps starting by changing the title, to something like “List of units of measurement that are unusual, strange, or remarkable in any particular way”?

David Olivier (talk) 09:22, 21 July 2010 (UTC)


 * I noticed that got removed, and had looked at the differences. I agree this article is a bit of a hodge-podge, but then that is allowed by a list, so I see no problem with that.


 * I tried above with another editor to come to some consensus on what is and is unit of measure is; without that it is hard to even start defining whether one is unusual.


 * For myself I take rather an inclusionist approach. Would you say "metres per second", for example, or "miles per hour", are units of measure? Some would argue that they are not. I would argue they are and I would have the weight of the SI behind me: they are derived units of measure. Some are clear by the name (this dimension divided or multiplied by that one), some are more hidden (the joule, newton, gray and so on).


 * So, taking as common ground that miles per gallon and litres per hundred kilometres are derived units of measure, what makes them unusual?


 * First let's rule out the dimensionality thing: litre = volume so D3 and then kilometre = D so that D3/D = D2 so it's an area. Fine, but that's not unusual, in my opinion: I suppose it's only unusual when you come to think about it, i.e. it's a bit unexpected to find that fuel consumption is an area and you think well, an area of what?. It could I suppose be quite funny to express fuel consumption in football pitches or the size of Wales, etc. But to me its dimensionality is not unusual, lots of fairly common things end up having rather odd dimensionality, and ultimately we can change the base dimensions we use as long as we have no fewer than necessary (we could use the metre-second as a base dimension and derive the metre from that, for example), and we aim not to have more than necessary.


 * Well, in my view, two things make the conversion unusual: first that they are individually common and second that one is a reciprocal of the other. This last is the most unusual and I think, of course this is just my opinion, is the reason that mpg is still advertised in the UK by manufacturers, although the small print always contains fuel consumption figures in litres per 100 km. Because it is reciprocal it does not lend itself to ready-reckoning in the way that, for example, degrees Fahrenheit might be reckoned as twice degrees Celcius plus thirty, for everyday use on weather temperatures, cooking and so forth. (I know that is not the exact definition, tht is the point; my recipes are all in Fahrenheit and my cooker is in Celcius so I am forever ready-reckoning things like that; and my scales measure only Imperial but recipes are often in metric; let alone that some of my measuring jugs are in US pints and cups so I have a constant juggle when the recipe calls for a pint of something).


 * So, I think perhaps the most appropriate place for this is Metrication in the United Kingdom, because of the prevalence of mpg in motor trade ads but the (I think) legal requirement to quote in l/100km. It would be good to get some kind of RS on this, I am not sure where to start (perhaps the ad trade journal "Campaign" or "Which?" magazine?).


 * In summary, I don't think the units are unusual, I think their conversion is. I agree it's worth noting somewhere, with due caution to OR (I don't think your plain facts constitute OR since they are built into the definition) and ideally some RS on the prevalence of the mix of use in the UK, and perhaps the Republic of Ireland, I don't know what the common use is there (indeed I don't know what they use in Australia or New Zealand, other places that had the imperial system of units until relatively recently but are now entirely metric).

Si Trew (talk) 10:13, 21 July 2010 (UTC)

When I originally re-factored the article header a couple of years ago (saving the entire article from a deletion vote as a result), I don't think I said anything about it being "deliberately not exact". I'd love to know who added that bit. Going purely by memory of events back then, the plan was:


 * Split off units and definitions intended for humorous effect.
 * Units that are notable primarily because they are historical should be left to an appropriate article on historical units.
 * Units that are notable primarily because they are foreign should be left to an appropriate article on foreign units.
 * Organise things so units that are directly convertible to SI units are sorted.
 * Add a basic definition that excludes figures of speech (removing such quaint items as "a fly's arse", "red cunt hair", and the like). The basic criteria for this was to exclude entries that don't routinely allow for an arbitrary number (within the limits of the scale ranges in which that unit could be used) associated with the unit in question.
 * To address some items specifically noted here, SI-imperial hybrids was left in because the SI prefixes were never officially approved for use with imperial units and vice versa. "light-nano-second" was left in because the base unit (light second) is not normally used for measuring such small distances.
 * miles per gallon and litres per 100 km are both in standard usage within their industries (mpg less so due to metrication, but in its day, it was the standard). Neither uses any unusual prefixes or suffixes, X per Y is a standard way to express ratios with units of measurement, and neither ratio combines units from disparate standards of metrology.

I suspect there may be some humour value in the idea that fuel consumption can be considered a unit of area. With suitable cites, that would make it a candidate for the humorous units article.

Rhialto (talk) 10:36, 21 July 2010 (UTC)


 * I didn't really see the fuel consumption = area part as humorous, but rather as thought-provoking. A bit like the hertz per dioptre entry: it makes one wonder - How can that be? But then if you see a dioptre not as referring specifically to lenses, but as a simple unit of spatial frequency under another name, then you can imagine a line marked at a certain spatial frequency; if you run along the line, you cross those marks at a certain frequence in time. The speed is the ratio of those two frequencies. That makes the hertz/dioptre measurement understandable. The same goes for fuel consumption translating to an area: a car consuming 10 liters per 100 km, which is 0.1 mm2, would guzzle up a strip of fuel 1mm wide and 0.1mm high running in front of it; presuming that the fuel does not evaporate along the way!
 * That doesn't say where the fuel consumption item should fit in. It may be OK for a page to be a list, but then shouldn't the list be at least minimally well-defined? Perhaps splitting into several pages, maybe along the lines suggested by Rhialto, would be best. Maybe we should try to list all the entries currently on the page and see how they would fit into those suggested categories?
 * Perhaps there should also be a section or a seperate page for “units with another name“ - units like the dioptre, or the hertz, which are used with a specialized meaning (dioptres for focal lengths, for instance), but are in fact just common units in disguise. Gallons per mile might come into this category: who would measure, say, the section of a wire in gallons per mile? Radians too: a radian is actually just another name for the pure number 1.

Size of a walnut
I was given the idea that a dinosaur brain "the size of a walnut" is a standard unit of measure, but can't seem to find any sources for this. I did a lot of searching, and lots of sources use it, but they don't say anything more about what that means, or that there's a standard for it. Hires an editor (talk) 17:58, 23 July 2010 (UTC)


 * A good ref here perhaps:


 * However despite saying dinosaurs' brains were probably about the size of a lime, it does not define how big a lime or a walnut should be taken to be.


 * Some cookery articles tend to define it as 2 tbsp, so I suppose 50 ml (2 oz). That's a volume of course and not a "size" in the sense of surface area or individual dimensions length, breadth, height (or three radii if we are assuming the brain or nut is approximately ellipsoid).


 * The Wikipedia article Walnut states that most commercial walnuts come from the Persian variety, which narrows it down a bit, but then goes on to call them "English walnuts".


 * National Geographic has an article giving the dimensions of a male octopus (Tremoctopus violaceus) the "size of a walnut":




 * There it is given as being 2.4 cm (0.9 in) long.


 * Si Trew (talk) 19:52, 23 July 2010 (UTC)

The dinosaur brain/walnut factoid doesn't really show the walnut is a unit of measure; it's just a simple comparison. Now, an article saying something was the size of (arbitrary number) walnuts -- that would be a relevant factoid. Rhialto (talk) 12:50, 15 March 2011 (UTC)

Football field (and others)
This subheading (and a few others) feel a little crufty. I have no dounbt that (for example) a "football field" is 100 yards, but to be considered a valid entry for this article, what is needed is a reference that says "a somethingorother is three football fields long" or "a somethingorother is the length of three football fields". Many cites on this page simply say "named object is so many yards long", which isn't anything l;ike saying the named object is a unit of length, even informally. Yes, these thinsg may well exist as units, but cites are needed. Rhialto (talk) 08:39, 14 March 2011 (UTC)
 * Sources would be good, and surely not too hard to find, but it's important to note that generally the football field measurement is not used for distance, but for area. It's in both sections of the article. It's reasonably well sourced in the Area section. I would actually question its presence in the Length section. HiLo48 (talk) 10:34, 14 March 2011 (UTC)

Kardashian (time)
Quite apart from it being a humorous unit, and so not appropriate for this article (there is a separate article for humorous units), this unit has only a single example of usage. That isn't enough to make it a broadly enough used entry for inclusion in any article. Even if the source being cited is notable (and that's just a single source, not 'multiple independent sources'), the unit itself isn't. Rhialto (talk) 08:31, 30 January 2012 (UTC)

Dog year
"it is also not unheard of to have the 52-day unit be identified as a 'human year' and the full 365-day year as a 'dog year.' " Even before you get into issues like non-linearity and breed dependence, I'm inclined to disagree with this way of describing it. It would seem that whoever edited it to use this phrasing thinks I'm 227 human years old.

Here's my interpretation. When a human year is the smaller unit, it's a unit of age, as distinct from a unit of time. In particular, it's the amount a human ages in a year, and a dog year is the amount a dog ages in a year.

Moreover, while the first terminology (dog year is the smaller unit) seems to be the more popular, I have found the second (human year is the smaller unit) to be supported by more sources, as well as making more logical sense. If we're going to claim that one system is the "typical convention", we ought to find a source for this claim.

Focus
There appears to still be some confusion about appropriate content for this page e.g; unusual vs. "humorous" which is designated as a "sub-article," and what precisely that means. Humor is highly-subjective, and some might find any one of the unusual units absurd and funny, therefore trying to make an editorial decision to separate some of the units seems misguided. Particularly as it results in duplicate and/or split content. A single well organized page or category (with a page per class e.g; time, volume, length) seems much more reasonable. Similarly, oughtn't the page be transcluding introductions from those pages for which a main article exists, rather than duplicating effort to summarize? --Belg4mit (talk) 14:31, 29 April 2012 (UTC)


 * The split is logical. If the intent of the unit's creator was humorous, then it goes in the humorous units article. This can be objectively researched, unlike the subjective view ("Do I find this funny?" vs. "Did the author intend this to be funny?").


 * I am undecided on the transclusion question.

Are citations realy necessary for some of the elements of the article? I refer particularly to "scoop"- which is a unit of measurement used primarily at a fruit and veg market. There is no written corpus of sources about fruit and veg markets that I am aware of, so what would be an acceptable citation? Anybody able to could visit the market and vouch for the existence of scoops. A quick web search found a few discussion comments about Lewisham's £1 scoops. However, this hardly represents a more authentic source than a wikipedia contributor, so what would make a citation legitimate? Many of the measurements in this article are informal, colloquial and verbal- very few are used in any official capacity and most seem to be mere approximations anyway.


 * Believe or not, yes, cites are very necessary. If it can't be cited because of its nature, it's not a suitable topic for an encyclopaedia. Bear in mind there are certain WP rules regarding the reliability of a cited source. Rhialto (talk) 15:12, 31 May 2012 (UTC)

Tatami
Support tatami removal. Besides being non-English, it is far from being "unusual", if we accept a global POV: it is standard in Japan. Staszek Lem (talk) 17:45, 1 August 2012 (UTC)
