WebOriginally, Anders Celsius assigned zero to stand for water’s boiling point and 100 to stand for water’s freezing point. This was later reversed by Carolus Linnaeus (or Carl Linnaeus), a Swedish botanist, physician, and zoologist after Anders died. So, 100ºC is now the boiling point of water, while 0ºC is the freezing point of water.
