Fahrenheit to Celsius
°F ↔ °C with common temps for weather, cooking, and body temperature.
98.6°F = 37°C · 37°C = 98.6°F
Common temperatures
| Reference | °F | °C |
|---|---|---|
| Water freezes | 32 | 0 |
| Normal body temperature | 98.6 | 37 |
| Water boils (sea level) | 212 | 100 |
| Moderate oven | 350 | 176.67 |
| Hot oven | 425 | 218.33 |
| Same on both scales | -40 | -40 |
How it works
C = (F − 32) × 5/9. F = C × 9/5 + 32 (NIST SP 811).
Example: 98.6°F = 37°C. At −40 both scales match.
