Talk:Rotherhithe Tunnel

YouTube Video
See article page history. The video is fine but the soundtrack is a commericial song and subject to copyright and therefore a copyvio. Please see WP:C for relevant policy. I have removed the link again although a silent version would be absolutely fine - does anyone have the means/interest in creating this? Thanks. --Spartaz 06:42, 4 January 2007 (UTC)

Unit Changes
I have reinstated my reverted changes, as they are consistent with established Wikipedia guidelines.

The units of measurement style guide (WP:UNITS) makes clear that SI and SI-accepted units should be used in UK-related articles as the primary measurement system in all cases except for a few specific exceptions. Tunnel dimensions are not an exception and therefore should be stated primarily in SI (metres).

Speed limits are one of the exceptions, but should have a undefined undefined template applied so the rest of the world can understand.

By the same token, it is appropriate to include the equivalent percentage gradient (2.78%) alongside the traditional "1 in 36" ratio, as this is the notation used on road signs throughout most of the world, including the UK since the 1970s.

 * WP:UNITS also states "For topics strongly associated with places, times or people, put the units most appropriate to them first." As the Rotherhithe Tunnel was constructed before the UK partially adopted the metric system, it was constructed using imperial measurements, and therefore imperial units are the primary measurement in this topic. You are welcome to make conversions per the guidelines, but blatant tenuous editing will be reverted. Jeni  ( talk ) 16:25, 18 December 2009 (UTC)


 * That's only part of what WP:UNITS states. The rest clarifies: "In the UK, [the most appropriate units to places, times or people] are more often metric units, with imperial units for measurements such as road distances and personal height and weight. See the examples in Metrication in the United Kingdom and the Times Online style guide under 'Metric'."


 * Both reference documents make clear that feet are only the UK primary units for personal height and aircraft altitude; for everything else (except road distances), metres are the primary unit. The construction date of the artefact being measured is irrelevant.


 * However: "nominal and defined values should be given in the original units first, even if this makes the article inconsistent". Were all defined measurements in feet quoted by the source texts of this article?


 * I also note that the undefined undefined tag on the speed limit and the equivalent percentage gradient have been reverted again. I assume this was an oversight while reverting the above changes, so I've re-instated these only for now.
