Réaumur gets very little mention these days: https://en.wikipedia.org/wiki/R%C3%A9aumur_scale

(I'd like to know what these guys were thinking when it came to deciding on the number associated with the boiling point of water, though. 60 and 80?)

60 is a pretty useful base with many factors. Not sure if that is a very useful property for expressing temperature, but it's not a completely random number either.

I worked in a factory that didn't have decimal points on the thermostat for the ovens.

It was sooo much harder to make foam in Canada than in the US as a result.

I know that is an ancient problem, but this was only a decade ago....

Kind of blows my mind the rest of the world doesnt use decimals when talking about the weather.

The problem with Celsius is that nice weather in Fahrenheit is 70 to 80, but in Celsius it's only 20 to 25. 5 degrees is too narrow to talk about the difference between a little too cool and a little too hot!

For cooking in ovens or whatever, it's fine because you're up at 350/175 or 500/250. Once you're up that high, precision doesn't matter.
