boiling water is also a fairly important temperature, and it doesn’t take much brainpower to figure out roughly where between freezing and boiling you like to be.
Plus it’s nice to have the reference points be quite objective, you can create a celsius thermometer that’s reasonably accurate without much work, and i feel like it makes relating to temperatures outside the scale easier too.
The amount of energy it takes to bring a volume of water from freezing to boiling is plainly observable and has a nice size for comparing to e.g. the melting point of metals.
