How to convert Fahrenheit to Celsius
Subtract 32 from the Fahrenheit temperature, then multiply by 5/9. For example, (72 °F − 32) × 5/9 = 22.2 °C, and (350 °F − 32) × 5/9 = 176.7 °C. Water freezes at 32 °F (0 °C) and boils at 212 °F (100 °C) at sea level.

Good to know
For a quick mental estimate, subtract 30 from the Fahrenheit value and halve it: 70 °F becomes 20 °C, against an exact 21.1 °C. The estimate drifts the further you get from room temperature, so use the converter for cooking and medical readings. A change of 1.8 °F equals a change of 1 °C.
Frequently asked questions
