It makes more sense in terms of our perception. But from a science perspective ~~Klevin~~ Kelvin makes more sense since you can't go lower than 0 K and negative temperature doesn't really make sense, since it'd mean something like negative energy.

A mistake plus Klevin gets you home by 7

Negative absolute temperature is a thing. Lasers exhibit negative temperatures when active, i.e. the lasing medium has a negative temperature expressed in Kelvin. Adding more energy doesn't increase its entropy, it just turns into more laser light. Any such system with bounded entropy can have a negative thermodynamic temperature.

I had a suspicion there was going to be a response like this. Never heard of it but sounds very interesting.
I doubt I'll properly understand it without a good YouTube video. I shall embark on a search

Yeah but from an every day perspective you've basically got 250 or so units there for no reason.
