Usually Timely.
Usually Scraped, Gleaned And Pilfered From Social Media.
Dude got two out of three right. F is measured with zero being as cold as water can go without freezing.
0C is the freezing point of pure water. 0F is the freezing point of water with a boat load of salt in it. "pure" water wasn't really known. 100F is the temperature of the healthy human when probed.
Because F was invented first, they didn't know if boiling water was the same each and every time. But they knew they got the same value every time they measured a human.
212 degrees F is the boiling point of pure water at standard atmospheric pressure. 32 degrees F is the freezing point of pure water at standard atmospheric pressure. 0 degrees F is the freezing point of a solution that is equal parts water and salt.
Fahrenheit originally set his scale so the freezing point of water was 30, and normal human body temperature 90. These were [obviously] subsequently revised.
