How to Convert Fahrenheit to Celsius
Fahrenheit (°F) and Celsius (°C) are both temperature scales. Unlike length or weight, temperature conversions require a formula rather than a simple multiplication factor. For quick reference: water freezes at 0°C (32°F), room temperature is about 20-22°C (68-72°F), body temperature is 37°C (98.6°F), and water boils at 100°C (212°F).
Conversion Formula
This formula accounts for the different zero points and scale sizes of the Fahrenheit and Celsius temperature scales.
Step-by-Step Examples
0 °F = -17.78 °C
Using °C = (°F − 32) × 5/9: 0 → -17.78
100 °F = 37.78 °C
Using °C = (°F − 32) × 5/9: 100 → 37.78
37 °F = 2.78 °C
Using °C = (°F − 32) × 5/9: 37 → 2.78
Common Use Cases
- Weather temperature conversion (e.g., 30°C = 86°F is a warm day)
- Cooking and baking (e.g., 180°C = 350°F for baking)
- Scientific and laboratory work
- HVAC and engineering (e.g., thermostat set to 21°C = 70°F)
