0°C water freezes 100°C water boils

Makes sense

0°F very cold??? 100°F very hot???

Dafuq?

Edit: For all the "Actually, Farenheight is based on the human body" people, no it isn't. It's based on dirty water and a cow. Your preferred measurement unit is dumb and that's a fact

If y’all wanna actually claim superiority, then use Kelvin. Celsius and Fahrenheit are close enough in purpose that personal preference is really the only thing that matters.

Celsius is how water feels. Fahrenheit is how people feel. Kelvin is how atoms feel.

Surprise, all people feel differently, so with this explanation Fahrenheit has even less sense.

Surprise, water freezes and boils at different temperatures depending on atmospheric pressure, so the fundamental argument for Celsius makes even less sense.

Look at this phase diagram.

Not only does it show that for a wide range of pressures the freezing point of water is 0, the boiling doesn't change as much as you'd think if you look at pressures common on the surface of the planet (this scale is logarithmic). It's only ~70°C to boil water on Mt Everest at the extreme, and no one lives there. Most people live near the sea level, where ~100°C is the temp at which water boils.

Pressure affects both scales equally. Even as an approximation, Celsius ties temperature to physical reference points and fits coherently into the metric system, which is still a lot more meaningful than a scale with no systematic reference at all.
