Frequently Asked Questions (FAQ)
Q: When using {{convert}} why does the answer not seem right sometimes?
A: This template takes into account the precision of the supplied value and generally rounds the output to the same level of precision. If you need to change from the default output precision, see Help:Convert.
Q: What are all the possible units (kg, lb, m, cm, ft, in, °C, °F, km, mi, nmi, mph, km/h, and so on)?
A: See: Help:Convert units.

g-force[edit]

Is there a conversion for acceleration from g to m/s2 ? Thanks.  Stepho  talk  00:47, 6 July 2016 (UTC)

Yes, it's g0 (g zero) with alias "standard gravity", although it is an acceleration unit and does not output "g-force".
  • {{convert|100|standard gravity|m/s2}} → 100 standard gravities (980 m/s2)
  • {{convert|100|g0|m/s2}} → 100 standard gravities (980 m/s2)
  • {{convert|100|g0|m/s2|abbr=on|lk=on}} → 100 g0 (980 m/s2)

Thank you, that works perfectly.  Stepho  talk  04:14, 6 July 2016 (UTC)

C-change parameter[edit]

In the article Geography of Norway#Climate, I've encountered some erroneous conversions between Celsius and Fahrenheit.

It said, for example, that 3 degrees Celsius is 5.4 degrees Fahrenheit. This is incorrect.

When I went to fix it by editing the article, I found out that it uses the Convert template, with the "C-change" parameter.

As in: "Convert|3|C-change".

Why does this produce a wrong result? Is there something I'm missing about this template?

In the meantime, I've removed this parameter from the conversion.

Please explain.

@Sentient Planet: There is nothing wrong with the template or the use of "C-change". Remember, the paragraph is discussing a difference in temperatures, not an absolute temperature. In other words, the difference between the two locations in January is 14.6 °C (26.3 °F) (−0.2 - −14.8 C / 31.6 - 5.4 F) and the difference in July is 2.9 °C (5.2 °F) (13.1 − 10.2 C / 55.6 - 50.4 F). I've changed the article back, while using flipped Fahrenheit temps to get more precise numbers while keeping Celsius first. Huntster (t @ c) 07:47, 20 July 2016 (UTC)
Thanks Huntster. For example, a temperature rise of 5 °C is the same as a rise of 9 °F. Consider:
  • {{convert|5|C-change}} → 5 °C (9.0 °F)
  • {{convert|5|C}} → 5 °C (41 °F)

@Huntster: Ah, right. I understand now. Thanks for clarifying the situation and reverting my edit. Sentient Planet (talk) 18:09, 20 July 2016 (UTC)

This discussion illustrates one reason why many engineers prefer to use the unit "K" (Kelvin) to identify temperature differences. This avoids confusion with absolute temperatures with the unit "°C". (It will however not help when either is converted to °F.) --136.8.33.71 (talk) 12:28, 26 July 2016 (UTC)

If K were the sole solution, this template would be superfluous. -DePiep (talk) 21:17, 26 July 2016 (UTC)
The Rankine scale is the Fahrenheit equivalent of Kelvin. But both Kelvin and Rankin are practically unknown to the general public.  Stepho  talk  01:13, 27 July 2016 (UTC)
