Rail transport modelling scales - HOn2
Dear Alpreston,

With editing Rail transport modelling scales, you broke the  gauge conversion template which currently can only accommodate the rounded 7mm:. If the exact 0.1 mm difference is important to you, please discuss at Template talk:Track gauge and provide proper references supporting this definition.--Aaron-Tripel (talk) 20:34, 3 October 2014 (UTC)

I have no idea how to do what Aaron Tripel is asking me to do. i.e. how to discuss the subject at Template talk:Track Gauge or how to respond directly to his message to me (yes, I have visited both pages - the layout doesn't make sense to me). I should also add that nothing on the page indicated to me that any form of template was in use. BTW, the figures I entered, 0276 inches(7.01mm), are taken directly from the NMRA Trackwork Standard sheet S-3. Alpreston (talk) 05:24, 5 October 2014 (UTC)
 * Hi Alpreston, the "template" Aaron is referring to is the piece of code stated above. I would recommend that you round off your units, because that 'piece of code' does not support decimal places. If you still want to discuss it (which I would not recommend you do, because there seems to be agreement to round off units), go to that page, and click "new section" on the top right hand corner. If you still need more help, please replace the help me template above. Thanks! Darylgolden(talk) 08:26, 5 October 2014 (UTC)


 * Hi, Darylgolden and Aaron-Tripel. I personally have no problem with further rounding the metric gauge figure to 7mm for the purposes of this article. The 7.01mm figure was entered because that's the metric approximation given in the relevant National Model Railroad Association standard sheets (Standards S-1 and S-3). The NMRA standard for HOn2 gauge is specified as 0.276 inch minimum (preferred)/ 0.285 inch maximum. I was involved in getting that standard adopted and thought prior to the vote that it should be set to 7mm. However, as it was pointed out to me at that time, NMRA standards are always specified in inches and thousandths of an inch. All the metric equivalents shown in parentheses on some (not all) NMRA standard sheets are simply derived from the inch dimension, rounded to the nearest tenth or hundredth of a millimeter.  Manufacturers producing products for the North American market are supposed to use the inch dimensions, not the metric; the NMRA is after all an American organization, although modellers here in Canada and some other countries use their standards for compatibility. While we're at it, since HOn2 products have been made commercially, albeit in limited, special order, quantities, the final statement in the HOn2 entry is also erroneous: the words "No known" should be replaced with "Very little" or something similar.)

 * OK. Feel free to replace the final statement.--Aaron-Tripel (talk) 17:32, 6 October 2014 (UTC)
