Fahrenheit to Celsius
Convert temperatures from Fahrenheit to Celsius. Includes conversion formula and common reference temperatures.
About the Fahrenheit to Celsius
To convert Fahrenheit to Celsius, subtract 32, then multiply by 5 and divide by 9. The order matters: the subtraction comes first because the Fahrenheit scale starts 32 degrees above the Celsius zero point.
For a rough weather estimate, subtract 30 and halve: 80 F becomes about 25 C, close to the exact 26.7. Recipes from the United States often give oven temperatures in Fahrenheit, so converting is a common kitchen task.
32 F is 0 C, 68 F is 20 C, 98.6 F is 37 C, 212 F is 100 C, 350 F (a common baking temperature) is 176.7 C and 425 F is 218.3 C.
Tips for best results
- Fan ovens are often set about 20 C lower than conventional ovens, so check your oven's guidance when converting recipes.
