100 Celsius to Fahrenheit
100 degrees Celsius equals
212°F
212 degrees Fahrenheit
100°C is 212°F, the boiling point of water at sea level. Water boils lower as altitude rises, which is why high-altitude recipes call for longer cooking times.
How to convert 100°C to °F
Formula
°F = °C × 9/5 + 32
Substituting 100°C
- 100 × 9/5 = 180
- 180 + 32 = 212
The two scales differ in both their zero point and their step size. A Fahrenheit degree is 5/9 the size of a Celsius degree, and the scales are offset by 32 degrees at the freezing point of water — which is why the conversion needs both a multiplication and an addition.
How 100°C compares
| Reference point | Temperature | Difference |
|---|---|---|
| Freezing point of water | 0°C / 32°F | 100°C (180°F) warmer |
| Room temperature | 21°C / 69.8°F | 79°C (142.2°F) warmer |
| Body temperature | 37°C / 98.6°F | 63°C (113.4°F) warmer |
| Boiling point of water | 100°C / 212°F | same temperature |
