Water boils at about 100 °C (212 °F) at normal sea‑level atmospheric pressure.

Quick Scoop

  • At sea level, the boiling point of pure water is defined as 100 °C, more precisely about 99.97 °C.
  • In Fahrenheit, this is 212 °F.
  • The boiling point changes with pressure:
    • At higher altitudes (lower pressure), water boils at a lower temperature (for example, around 93–94 °C at about 1,900 m elevation).
* On very high mountains like Everest, it can be as low as about 71 °C.

* In a pressure cooker or high‑pressure system, water can boil well **above** 100 °C.

So if you’re near sea level, you can safely think “water boils at 100 °C / 212 °F,” but the exact temperature depends on altitude and pressure.
