Understand how altitude impacts water's boiling point with our easy-to-use calculator. Perfect for cooking, camping, or scientific experiments, this tool helps you accurately determine the boiling temperature of water at various elevations, ensuring precise results every time. Input your elevation in meters or feet and get instant results in Celsius or Fahrenheit.
Formula:
The boiling point of water decreases as altitude increases due to lower atmospheric pressure. A common empirical approximation states that the boiling point decreases by approximately 0.5°C for every 150 meters (or 0.9°F for every 500 feet) increase in elevation above sea level.
This calculator applies these empirical relationships:
- Boiling Point (°C) = 100 - (Altitudem / 150 × 0.5)
- Boiling Point (°F) = 212 - (Altitudeft / 500 × 0.9)
Where Altitudem is the altitude in meters and Altitudeft is the altitude in feet.
