Water boils at about 100 °C, which is 212 °F, at normal sea‑level atmospheric pressure (around 1 atm).

Quick Scoop

  • At sea level, the normal boiling point of pure water is 100 °C (212 °F, about 373 K).
  • The exact thermodynamic value is about 99.97 °C (211.95 °F), but everyone rounds it to 100 °C.
  • Boiling point changes with pressure:
    • Higher altitude (lower pressure) → water boils at a lower temperature (for example, around 71 °C / 160 °F on Mount Everest).
* Below sea level or in a pressure cooker (higher pressure) → water boils at a higher temperature (just over 100 °C).
  • Dissolved stuff like salt raises the boiling point slightly (salt water can boil around 102 °C under normal pressure).

So if you’re at typical everyday conditions near sea level, you can safely treat the boiling point of water as 100 °C or 212 °F.
