It's what someone might come up with without a scientific definition. Think of 0 - 100 F being (very very roughly) the survivable range for humans without special precautions beyond normal winter/summer clothes. -18 - 38 C is way more arbitrary from that perspective.

They said there's no intuition there, I gave them one. I didn't say this was how it was defined, just how it could make more sense in daily life than the Celsius range without relying on familiarity.

Conclusion before reasoning. post-hoc.

I can do it too.

- 0C - 30C are nice round numbers that are much better numbers for human comfort than 0F and 100F are. - above 0C in the winter means "it's going to be messy outside", and is the most important number. - 100C is an important number for cooking - a degree C is a reasonable interval. People using degrees F tend to round to multiples of 5, which is too large especially around room temperature, but a single degree F change is imperceptible.
