Only in america, though. The rest of the world has a more diverse climate and it actually gets proper hot and cold here.

So in To Build A Fire when it's -70° it doesn't matter what it is, the sad hidden ending is the dog freezes too.

It's actually kinda weird that they use dollars and cents and not pounds, shillings, pennies and farthings, because that feels much more compatible with the imperial way of thinking.

Imperial basically developed by picking a useful measure at each given scale.

For example, a mile was originally 1000 paces, and wasn't standardized at all. The first Roman legion to march down a road would stick mile markers down based on the length of their stride.

A furlong was one agricultural furrow long - the distance you'd plow with your Ox.

A foot was originally someone's literal foot.

It's inconsistent for the same reason a meter doesn't go neatly into a light year. That doesn't make it good, but it's a very human system of units.

At the very least get the history right. Fahrenheit was defined so that a temperature stable brine solutions temperature was zero, because it was easy to create for calibration, and that the freezing and boiling points of water would be 180° apart, because circles and temperature gauges have a natural link.

Redefinition of the scale to make it line up with metric has led to some minor drift in the definition.

The good criticism of fahrenheit is that it's non standard, not that it doesn't have round numbers for two states of one substance.

That doesn't make sense at all lmao

I see what you mean, but the freezing point of water is arguably the most critical temperature when it comes to weather. Celsius is easy in this regard.

+3°C? => Precipitation will almost certainly be liquid.

-3°C? => Precipitation will be mostly solid and any possible rain or drizzle will be supercooled, forming a sheet of ice on whatever it lands on. Look out for slippery roads!

It's also useful that a moderate climate on average won't go much higher than 100 in the summer, or lower than 0 in the winter. So you know if it does then either that day is an outlier, or you don't live in a moderate climate. So it makes that information just a bit more intuitive. Speaking as a Michigander at least, that's what those numbers mean to me.
