What's so special about 0 - 100?
40° of civilized units sucks, but is still perfectly survivable and is becoming more and more common in some parts of the world. That's 104° of fucked up units.
Negatives up to -30° are also common around the world and I frequently went out in shorts and t-shirt in -10° for a short time to grab mail or take out trash.
The only sort of reasonable justification for F units I've ever heard was that there's less of a change between whole degrees, but decimals are not exactly hard to figure out imnho.
Americans are out here needing 100 degrees of magnitude between "it's really cold outside" and "it's really hot outside" while ignoring the scientific uses of anything outside of those values and you expect them to understand decimals?
How many "it's really hot outside" until iron melts, or water boils, or meat cooks? Fuck knows. But I'll be damned if I use punctuation in my maths, this country was founded on addition and subtraction and that's all the founding fathers ever needed, now gtfo with your letters and periods and symbols in my mathematics.

Who cares, we don't need to know that at all in daily life.

If we don't need to why would we? Base-10 isn't a virtue for a temperature measuring system mainly used to tell how it feels for a human to exist in the world
