Web6 Answers. One reason you might think T should be measured in Joules is the idea that temperature is the average energy per degree of freedom in a system. However, this is only an approximation. That definition would correspond to something proportional to U S (internal energy over entropy) rather than ∂ U ∂ S, which is the real definition.
