The formulas

°C = (°F − 32) × 5 ÷ 9

°F = (°C × 9 ÷ 5) + 32

To turn Fahrenheit into Celsius, subtract 32, then multiply by 5 and divide by 9. To go back, multiply Celsius by 9, divide by 5, and add 32.

For example, 68 °F is 20 °C. Negative temperatures work too: −40 °F and −40 °C are the same temperature.
