MHB How to Convert 1/(ft*°F) to 1/(m*°C)?

[mk747pe]

Hi everyone,

so I have equation, let's say X and I want to convert it to SI units. Now X is in 1/(ft*°F) and I need 1/(m*°C). Ok, so I simply convert ft to m= 0.3048, but what to do about °F? 1°F is -17.2°C which will not work.
Any suggestions?

Thanks,
Miroslav

Hi Miroslav,

You must understand x as one unit per foot and per increase of one °F. (Absolute temperatures would not make sense : what if the temperature is 0°F ?).

You can then do as usual : one ft is 0.3048 m, and an increase of one °F is an increase of 5/9 °C (or °K).
