Fahrenheit to Celsius

To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9. For example, 68 °F is 20 °C, 98.6 °F is normal body temperature (37 °C), and 32 °F is the freezing point of water (0 °C).

A quick mental shortcut: subtract 30 and halve the result — 70 °F becomes roughly 20 °C. This converter gives you the exact value, useful for weather, ovens and science homework. The reverse tool converts Celsius to Fahrenheit.
