Eh, all the degrees (Celsius, Fahrenheit, Réaumur, etc) are all about equally bad. Nicest thing that can be said about Celsius is that it's decimal, connected to water (0=freezing, 100=boiling) so it plays well with the rest of metric.

Kelvin is actually the most practical of the lot, FSVO [1]. It's not a 'degree', because it's anchored at absolute zero. It's just a bit unwieldy for our day-to-day, with room temperature at 293K. But I can imagine if people were to grow up with it, it wouldn't be too bad even then.

[1] eg. "Why can an aircon still heat the house at ten degrees below zero?"- "Well akshually, you still have 263K of heat energy to pump, not an actual problem"

Right, we are just arguing which is the most practical range. It's like choosing a calendar: we could define one using entirely metric time units, but nobody would want to use it as long as human civilization is anchored on Planet Earth.
