Well, the definition of 0ºC is based on the freezing point of water at one atmosphere of pressure, which isn't super relevant on the Moon. You could give it in K but that's not very relatable.
-280F, -173C, or 100K is not relatable to anyone except niche researchers. Maybe slap in the extra few people who happen to work with liquid helium and you are still talking about 0% of the population.
