Boiling Point of WaterAlso equal to 373.15 Kelvin
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
