Boiling temperature of water in °C

depending on altitude, from -500 m to 12400 m

Numerical table based on the barometric levelling model. Calculated values represent the average state of the atmosphere.

Warning: latitude and weather conditions influence atmospheric temperature and pressure, which may alter the observed boiling temperature.

Example of table reading: What is the boiling temperature of water at an altitude of 1800 m ?

The decomposition 1800 = 1500 + 300 brings us to the intersection of the 1500 m line and the 300 m column, where we read the temperature of 94.0 °C.
