Scales

This is because Fahrenheit is based on a brine scale and the human body. The scale is basically how cold does it have to be to freeze saltwater (zero Fahrenheit) to what temperature is the human body (100-ish Fahrenheit, although now we know that’s not exactly accurate). Fahrenheit was designed around humans.Celsius and Kelvin are designed around the natural world.Celsius is a scale based on water. Zero is when water freezes, 100 is when water boils.Kelvin uses the same scale as Celsius (one degree, as a unit, is the same between the two), but defines zero as absolute zero, which is basically the temperature at which atoms literally stop doing that spinning thing. Nothing can exist below zero Kelvin. It’s the bottom of the scale.So.Fahrenheit: what temperatures affect humansCelsius: what temperatures affect waterKelvin: what temperatures affect atoms

Why didn’t my science teachers ever see fit to toss off this little fact?

Celsius is a scale based on water. Zero is when water freezes, 100 is when water boils.

Kelvin uses the same scale as Celsius (one degree, as a unit, is the same between the two), but defines zero as absolute zero, which is basically the temperature at which atoms literally stop doing that spinning thing. Nothing can exist below zero Kelvin. It’s the bottom of the scale.

So.
Fahrenheit: what temperatures affect humans
Celsius: what temperatures affect water
Kelvin: what temperatures affect atoms

Do not wear contact lenses if you are in a situation where you may be tear-gassed.  When I went through basic training, we were warned that there was a possibility the tear gas they were using could melt contact lenses.

BOOOOOOOOOOOST!!!!!!!!!!

That’s insane, please be careful y’all
