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.
Understanding Fahrenheit and Celsius Conversions
Converting measurements between metric and imperial scales, or relative temperature benchmarks, is essential in sciences, logistics, cooking, and daily travel. Using standard multipliers guarantees precision and alignment across different measurement systems.

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).
