How it works

°C = (°F − 32) ÷ 1.8

Water freezes at 32 °F, which is 0 °C, so first take away 32. Then divide by 1.8, because a Celsius degree is 1.8 times as big as a Fahrenheit degree. A quick check: an oven at 350 °F is about 177 °C.

  1. Subtract 32 39.79 − 32 = 7.79
  2. Divide by 1.8 (that is 9/5) 7.79 ÷ 1.8 = 4.33 °C
