Formula

°F = °C × 9/5 + 32

Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F). Normal body temperature is about 37 °C, or 98.6 °F.

Quick estimate

Double the Celsius value and add 30: 20 °C → 40 + 30 = 70 °F (exactly 68 °F). The estimate is close for everyday weather temperatures.

Where Fahrenheit is used

Fahrenheit is the everyday temperature scale in the United States and a few other countries. Ovens in American recipes are set in °F: 350 °F is about 177 °C.
