Talk:Carneddau

Moved this article from "Carnedd" to "Carneddau". I have never heard "Carnedd" used for the range. Rhion 08:15, 21 September 2005 (UTC)

I've heard 'Carneds' (with a 'd' rather than a soft 'th' sound) used by non-Welsh speakers but would baulk at using that pronunciation myself! Geopersona (talk) 05:07, 21 January 2009 (UTC)

Odd that the convert function is giving 910m for 3000ft whereas it should be 914m Geopersona (talk) 05:07, 21 January 2009 (UTC)

Conversion Precision

The area is described as extensive high ground over 2000 ft, 2500 ft and 3000 ft. Metric conversions have been added. Template:convert naturally rounds figures to match the input so {{cvt|3000|ft|m}} is displayed as, 'Template:Cvt' instead of the more accurate figure Template:Cvt. This was fixed by adding a precision parameter as {{cvt|3000|ft|m|0}}. Unfortunately the original figures are rough. That is, "High ground above about 3000 ft" rather than "High ground over 3002 ft 7 inches". So the metric figured should also be rough figures. Roughly 3000 ft is roughly 910 m or even roughly 900 m. Roughly 914 m 40 cm does not make sense. A good rule of thumb is that Ordnance Survey used 50 foot contours on their 1 inch series and now use 10 metre contours on the 1:50000 series so rounding heights of areas to 10 m makes sense.

However actual heights of features should always be converted with true precision. Infobox Mountain has parameters height_m and prominence_m that automatically convert metric height to imperial. This can be embarrassing if the precise height of a mountain is 1000 m. To avoid any rounding, you can add a decimal point so that the height is 1000. m. Don't add a prosthetic zero as otherwise you will get Template:Cvt. OrewaTel (talk) 19:43, 12 November 2023 (UTC)
