Boiling Point of Water

Charts giving the boiling point of water vs altitude are based on the standard atmosphere. If the barometric pressure is different from the standard atmosphere, the actual boiling point of water will vary from that given in the charts.

A more reliable way to determine the correct boiling point of water, at a specific time, is to use the calculator below. Just enter the current barometric pressure, in inches of mercury (inHg), and click on "Do Boiling Point Calculation". The correct boiling will be returned in the lower window.
You can visit The Weather Channel and enter your ZIP code to determine you current barometric pressure.
