Fahrenheit to Celsius: The Complete Guide
If you've ever read a weather forecast in °F and had no idea whether to pack a coat or sunscreen, this guide is for you. Fahrenheit to Celsius conversion is one of the most searched unit conversions on the internet — here's everything you need.
The Conversion Formula
°C = (°F − 32) × 5/9Equivalently: subtract 32, then multiply by 0.5556.
Quick Reference Table
- 32 °F = 0 °C (freezing point of water)
- 50 °F = 10 °C (cool day)
- 68 °F = 20 °C (comfortable room temperature)
- 86 °F = 30 °C (warm summer day)
- 98.6 °F = 37 °C (normal body temperature)
- 212 °F = 100 °C (boiling point of water)
The Quick Mental Method
Subtract 30, then halve the result. For example, 80 °F → 50 ÷ 2 = 25 °C (actual: 26.7 °C). Accurate enough for everyday use in the 40–100 °F range.
Oven Temperature Reference
- 325 °F = 163 °C (low/slow baking)
- 350 °F = 177 °C (standard baking)
- 375 °F = 191 °C (moderate-high)
- 400 °F = 204 °C (high heat)
- 450 °F = 232 °C (very high/broiling)
