Helpful Information

Fahrenheit to Celsius formula

°C = (°F − 32) × 5/9. For example, 72 °F (typical room temperature) = 22.2 °C, and 212 °F (water boiling) = 100 °C.

Common temperatures at a glance

32 °F = 0 °C (freezing) · 50 °F = 10 °C · 68 °F = 20 °C · 77 °F = 25 °C · 98.6 °F = 37 °C · 212 °F = 100 °C (boiling)

Shortcut

For a quick mental estimate, subtract 30 from the Fahrenheit value and halve it: 72 °F → (72 − 30) / 2 = 21 °C, close to the exact 22.2 °C.
