What makes Kelvin absolute, and why is Celsius "wobbly"?

I failed physics in high school

0 K is like when there is 0 heat basically, while celsius isn't. Imagine a unit for distance called "goob" where 0 goobs is 100 m and 1 goob is 115 m. In that case the goob unit would behave differently than a meter when you multiply and divide because 0 of the units don't actually correspond to "nothing" in a physical sense. That's exactly how the Celsius scale is, with zero being placed somewhere arbitrarily, not at a physical zero.

i feel like i need more goob in my life. do you sell rulers?

[–] Bumblefumble@lemm.ee 2 points 1 month ago

Bit of an awkward scale for a ruler, but I can sell you one from -6.6666666.... to -6.65 goobs.
