Entropy units

For the units of entropy can we also use kJ/K?

Re: Entropy units

I'm sure you can use kJ/K for entropy if it matches the units of everything else in the problem you are working on but the SI unit for entropy is K/J!

Re: Entropy units

Just make sure all the units match up/cancel out correctly.

Re: Entropy units

As long as all the calculations are correct and the units match up then you can use either one. However, changing units constantly may result in accidental mix ups, so you should be fine as long as you stay consistent

Re: Entropy units

Answer should be based on the units given in the problem. Joules can be represented in many units kJ, kg.m^2, s^-2, etc. Just identify what the question asks and have consistent units.
