Key Temperature Reference Points
Unlike lengths and weights which scale from zero proportionally, temperature scales have differing zero offsets. 0 °C is calibrated to the freezing point of water, while 0 °F was historically defined with brine, and 0 K is true thermodynamic absolute zero.
Water Freezing Point
0 °C = 32 °F = 273.15 K.
Human Body Temp
37 °C = 98.6 °F = 310.15 K.
Water Boiling Point
100 °C = 212 °F = 373.15 K.
