100° F was human body temperature, later revised somewhat with better measurements and a decrease of parasites . The average person in those days in London had a slightly higher body temperature than today
0F is not ocean freezing, is the freezing temp of a brine mix that he chose arbitrarily (some think that he chose that temp because it was close to the coldest his town had ever been and he used it to calibrate the scales of his thermometers)
0°F is when the ocean freezes

FYI, the ocean freezes at around 28F
Oceans freezing also depends on currents, and mixing of the water from the surface. 28° will freeze water in a room.
This is why often the ocean is not frozen at much lower temperatures.
I’m not at all cognizant of how 0 was decided
