when you're trying to find the entropy change of an ideal gas reversibly, do you use the equation with temperature in kelvin or celsius?

I believe that the units for entropy/entropy change are always in J.K-1 so the units should be in Kelvin. I haven't seen entropy in Celsius yet.

I believe that it needs to be calculated in Kelvin.

You should do the calculations with kelvin.
