What This Calculator Does
The Boiling Point Altitude Calculator determines the boiling point of water based on elevation. Water boils at a lower temperature at higher altitudes, affecting cooking times.
How It Works
The boiling point drops about 1 degree C for every 300 meters of elevation. Formula: BP = 100 - (Elevation / 300) x 1.
Example
At 1,500 meters elevation, water boils at 95 degrees C instead of 100 degrees C.
Formula
BP = 100 - (Elevation / 300)Reading the Results
Boiling Point
The temperature at which water boils at your elevation.
Fahrenheit
The boiling point in Fahrenheit scale.
Frequently Asked Questions
How much does boiling point drop per meter?
About 0.0034 degrees C per meter, or roughly 1 degree C per 300 meters.
Does this affect cooking?
Yes. Water boils at a lower temperature, so food takes longer to cook at altitude.
How do I adjust recipes?
Add 1 minute of cooking time per 1,000 feet above sea level for boiling foods.
