What is the Boiling Point of Water?

Water boils at 212°F at sea level, but only at sea level. Changes in atmospheric pressure will alter the temperature at which water boils. To use this calculator you will need your current pressure* and elevation.

*This calculator uses adjusted barometric pressure as typically reported by airports and news outlets
