Error Using unitConvert from Celsius to Fahrenheit.

When using unitConvert from Celsius to Fahrenheit and vice versa I noticed it was giving me incorrect answers. It is just multiplying or dividing by 9/5ths and forgetting to add or subtract the 32. Is there a way to fix this or is this a bug. Using the unitConvert() function and saw it appeared both 2023a and the mobile version.

You would do best to indicate which release you were using when you saw this.

Answer 1

The documentation for unitConvert() specifies that "By default, temperatures are assumed to represent temperature differences." This explains the reason why it doesn't apply the 32 degree offset. It further goes on to explain how to do an absolute temperature conversion. The example that is given is this:

u = symunit;
T = 23*u.Celsius;
absK = unitConvert(T,u.K,'Temperature','absolute')

absK = 

Or, a perhaps more obvious example would be:

T = 20 * u.Celsius;
absF = unitConvert(T, u.Fahrenheit, 'Temperature', 'absolute')

absF =

Try again. It seems correct to me in R2022b.

I should have clarified, I am trying to use the command/function unitConvert() which when going from Celsius to Fahrenheit converts 100 to 180 in both 2023A and the 2025 version on my tablet. I thought I had included it in the initial post but release must not have saved when I clicked it.
