If Daniel Fahrenheit based his scale off the Ole Romer scale, by multiplying the values by 4 (to avoid fractions), and then scaling them (to create 64 intervals between ice melting and body temperature, then how the fuck did he get the boiling of water to be 212 degrees?

Ice Melting -
7.5(x4)=30(scaled)=32

Body temperature -
22.5(x4)=90(scaled)=96

Water Boiling
60(x4)= for some reason 212 wtf??
