The Formula
°C = (°F − 32) × 5/9
Subtract 32 from the Fahrenheit temperature, then multiply by 5/9 (or divide by 1.8).
Common Conversions
- 32°F = (32−32) × 5/9 = 0°C (freezing point)
- 72°F = (72−32) × 5/9 = 22.2°C (room temperature)
- 98.6°F = (98.6−32) × 5/9 = 37°C (body temperature)
- 212°F = (212−32) × 5/9 = 100°C (boiling point)
Quick Trick
For rough mental math: subtract 30, then divide by 2. 80°F ≈ (80−30)/2 = 25°C (actual: 26.7°C).
