Fahrenheit to Celsius (°F to °C)
0 °F = -17.78 °C
Formula: °C = (°F − 32) × 5/9
How to convert Fahrenheit to Celsius
°C = (°F − 32) × 5/9
To convert, subtract 32, then multiply by 5/9. Example: 350 °F → 176.667 °C.
Subtract the 32° offset (the freezing point of water in °F), then scale by 5/9 because 180 °F span the same range as 100 °C.
Used for US weather, American recipes and oven dials, fever thermometers and pool or hot-tub settings.
Mental shortcut: subtract 30 and halve (is within about 1 °C between 32 °F and 70 °F; drifts further off for hot temperatures).

Frequently asked questions
What is the formula to convert Fahrenheit to Celsius?
°C = (°F − 32) × 5/9. In words: subtract 32, then multiply by 5/9. For example, 350 °F → 176.667 °C. Subtract the 32° offset (the freezing point of water in °F), then scale by 5/9 because 180 °F span the same range as 100 °C.
How do I convert degrees Fahrenheit to degrees Celsius?
Use °C = (°F − 32) × 5/9: subtract 32, then multiply by 5/9. Example: 350 °F → 176.667 °C.
Is there a quick way to estimate °F to °C in your head?
Yes — subtract 30 and halve. This is within about 1 °C between 32 °F and 70 °F; drifts further off for hot temperatures. Use the exact formula (°C = (°F − 32) × 5/9) when precision matters.
How do I convert degrees Celsius back to degrees Fahrenheit?
Use °F = °C × 9/5 + 32 — multiply by 9/5 (1.8), then add 32. See the Celsius to Fahrenheit page for a full chart.
