Fahrenheit to Celsius
Subtract 32 from the Fahrenheit reading, then multiply by 5/9. Freezing water is 32°F and 0°C. Boiling water is 212°F and 100°C.
32°F = 0°C · 212°F = 100°C
How to use it
- Type the Fahrenheit temperature.
- The converter subtracts 32 and multiplies by 5/9.
- Check the table before you change an oven or a thermostat.
- Use the Celsius converter to go back the other way.
Formula
°C = (°F − 32) × 5/9
Removing the 32° offset lines the scales up at freezing. Multiplying by 5/9 resizes the degree.
A 350°F oven
(350 − 32) × 5/9 = 176.667°C. Recipes that say 180°C are asking for about 356°F, a small step hotter than 350°F.
68°F is 20°C, a mild room. 72°F is 22.2°C. A fever often quoted as 100.4°F is 38°C. A 350°F oven is 176.7°C, close to the 180°C mark on a European dial. The scales cross at −40°F, which is also −40°C.
