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 43 − 32 = 11
  2. Divide by 1.8 (that is 9/5) 11 ÷ 1.8 = 6.11 °C
