Martin Hackworth reference[edit]

Martin Hackworth is a Physics Lecturer as Idaho State University. I obtained his prior permission by email to originate two new sections in this article "Temperature Lag" and "Differences in Variation" based on his published course notes. Dgiroux (talk) 01:45, 11 January 2009 (UTC)[reply]

Celsius[edit]

Lets change farenheit to C because no one in the world knows F — Preceding unsigned comment added by 64.228.217.19 (talk) 04:39, 24 February 2009 (UTC)[reply]

It should have both but in the example noted (Snake River, Idaho), they use farenheit so it certainly more appropriate to lead with F and offer a parenthetical conversion to Celsius. Agne ^Cheese/^Wine 05:46, 24 February 2009 (UTC)[reply]

In some places there are temperature differences instead absolute temperatures - isn't it usual in the englishspeaking world to use Kelvin then instead degrees Celsius? --79.240.119.38 (talk) 10:49, 11 November 2018 (UTC)[reply]

Decision #3 in the 13th Conférence Générale des Poids et Mesures (CGPM) states "a temperature interval may also be expressed in degrees Celsius". In parts of the scientific world it is apparently still common to use Kelvin in that way, although I've not personally come across it in the Earth sciences.

Improper use of {convert} function[edit]

Today I discovered (and corrected) 2 errors on this page. The page author used the {convert} function to display the difference between two temperature ranges. The result was 2 citations of a difference of 135F because 135 is the conversion of 57C. Although 57 is the correct difference between the cited Celsius numbers, the actual difference between the Fahrenheit numbers is 102, not 135. One must calculate the Farenheit difference manually. Using {convert} on the Celsius results in an incorrect value for the actual Fahrenheit difference.

I've not sought out other pages (yet) to see whether this use of the {convert} function may exist but I suspect it's an easy mistake to make and therefore likely a widespread error. Although I've had a Wikipedia user account since 2009, I've not been very active as an editor and as such, I still consider myself a novice user. Does anyone have any idea how we might search for, and correct, such misuses of the {convert} function site-wide?--Richh2 (talk) 18:09, 25 January 2016 (UTC)[reply]

Note that the "C-change" and "F-change" parameter values can be used for temperature differences. It doesn't (as of the time I'm typing this) display it the way I learned — using "C°" instead of "°C" — but at least the numerical conversions are done correctly. As for how to detect such errors, I doubt that could be done automatically, although a bot could probably be used to list any transclusions of the template close to words like "difference", "increase", "change", "range", etc. This could be discussed at Template talk:Convert (and probably has been already). - dcljr (talk) 05:36, 20 February 2020 (UTC)[reply]
