Boiling Point at Altitude Calculator

Find water's boiling point at a given altitude.

Boiling point (°C) 94.737

Boiling point (°F) 202.53

Formula: bp ≈ 100 − altitude ÷ 285 (°C)

Step-by-step with your numbers:

1. Values used:

2. Altitude = 1,500

4. Boiling point = 94.737°C

5. Boiling point = 202.53°F

Did we solve your problem today?

Water boils below 100 °C at altitude because air pressure is lower.

The math behind it

A handy approximation: water's boiling point drops about 1 °C for every 285 m of elevation.

1,500 m → ~94.7 °C.

Cooking impact?

Lower boiling temperature means food takes longer to cook at altitude.
