How it works
To convert fahrenheit (°F) to celsius (°C), perform the following calculation:
Formula
°C = (°F − 32) × 5/9
Method
Subtract 32 from the Fahrenheit temperature, then multiply by 5/9 (or 0.5556) to get Celsius.

Frequently asked questions
Subtract 32 from the Fahrenheit temperature, then multiply the result by 5/9 (or approximately 0.5556).
0°F is about −17.78°C; 32°F is exactly 0°C (the freezing point of water); and 100°F is about 37.78°C (near standard human body temperature).
For a quick estimate, subtract 30 from the Fahrenheit temperature, then divide the result by 2. For example, 80°F is about (80 − 30) ÷ 2 = 25°C (actual is 26.67°C).
