What is 100°C in Fahrenheit?
100°C equals
212°F
Boiling Point of WaterAlso equal to 373.15 Kelvin
100 degrees Celsius equals 212 degrees Fahrenheit. The Celsius scale is standard in most countries worldwide while Fahrenheit is used primarily in the United States. This conversion uses the formula: F = (C × 9/5) + 32.
100°C: The Boiling Point of Water
100°C (212°F) is the boiling point of water at sea-level standard atmospheric pressure. At this temperature, water transitions from liquid to steam (water vapor).
Key Facts About 100°C / 212°F
- • Boiling point decreases at higher altitudes (Everest summit: ≈ 70°C / 158°F)
- • Corresponds to 373.15 K on the Kelvin scale
- • The second reference point of the Celsius scale (0°C = freezing, 100°C = boiling)
- • Adding salt raises the boiling point very slightly
- • Pressure cookers raise the boiling point to about 120°C (248°F)
How to Convert 100°C to °F
Formula:
(°C × 9/5) + 32 = °F
- 1
Multiply by 9/5 (1.8): 100 × 1.8 = 180
- 2
Add 32: 180 + 32 = 212°F
100°C = 212°F
Reverse: 212°F back to °C
(°F − 32) × 5/9 = °C
- 1
Subtract 32: 212 − 32 = 180
- 2
Multiply by 5/9: 180 × 0.5556 ≈ 100°C
