How temperature conversion works

Temperature is the one category that is not a simple multiplication, because the scales start at different zeros. To go from Celsius to Fahrenheit, multiply by 9/5 and add 32; to go back, subtract 32 and multiply by 5/9. Kelvin is Celsius plus 273.15.

Useful reference points: water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F) at sea level, normal body temperature is about 37 °C (98.6 °F), and −40 is the same on both the Celsius and Fahrenheit scales.
