Boiling Point of Water as a Function of Altitude

altitude (ft)

0

When the elevation is (in feet)
0
and the atmospheric pressure is (in inches of Hg)
29.92
the boiling temperature of water is (in °F)
212.01

The boiling temperature of water decreases as the pressure decreases or as the altitude increases. For example, water boils at 212 °F at or near the sea level. In Oxford, Mississippi, where the elevation is about 505 ft., water boils at 211 °F. In Golden, Colorado, where the elevation is about 5600 ft., water boils at 201 °F.
