I think that the idea is "what it feels like in a scale of 0 to 100".
So, in Celsius, water are "very cold" (=freezing) at 0 degrees but "very hot" (=boiling) at 100 degrees.
Same with Fahrenheit: 0 is extremely cold while 100 is very hot.
I get the logic but I am too used to Celsius at this point, just like you.
