How to convert
To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9.
°C = (°F − 32) × 5/9
For example: (68 − 32) × 5/9 = 36 × 5/9 = 20 °C.
Handy reference points: water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F), normal body temperature is about 37 °C (98.6 °F), and −40 is the same in both scales.
In your head: Take off 30 and halve it: 70 °F ≈ 20 °C (exactly 21.1 °C). It’s closest for everyday weather.
When you’ll need it
American recipes give oven temperatures in Fahrenheit: 350 °F is about 177 °C (180 °C, gas mark 4), and 425 °F is about 218 °C (220 °C, gas mark 7).
