How to use

  1. Enter the altitude or height.
  2. Pick metres or feet from the unit dropdown — the result updates live.
  3. Read the air pressure in several units and the estimated water boiling point below.

Note: The barometric formula (ISA) is used. The boiling point is a rough estimate — the real value can differ slightly with pressure and weather.
