How to Convert Fahrenheit to Celsius

Fahrenheit and Celsius are two temperature scales used around the world. Knowing how to convert Fahrenheit to Celsius can help when reading international weather information, recipes, equipment specifications, or other temperature measurements.

Fahrenheit to Celsius Formula

Subtract 32 from the Fahrenheit temperature and multiply the result by 5/9.

°C = (°F − 32) × 5/9

Common Examples

• 32°F = 0°C
• 50°F = 10°C
• 68°F = 20°C
• 77°F = 25°C
• 86°F = 30°C
• 212°F = 100°C

Worked Example

For 95°F, first subtract 32 to get 63. Then multiply 63 by 5/9. The result is 35°C.

Negative Temperatures

The formula also works for cold temperatures. For example, 14°F converts to -10°C.

Checking a Conversion

You can verify the answer by using the reverse formula: °F = (°C × 9/5) + 32. This is useful when a temperature needs to be checked carefully.
