Boiling Point at Altitude: 100.0 °C

Temperature Drop: 0.0 °C

Boiling Point at Altitude: 212.0 °F

Calculation Formula

Boiling Point (°C) = Sea Level Boiling Point (°C) - 0.0065 × Altitude (m)

Where:
- Sea Level Boiling Point: The boiling point of water at sea level (100°C at standard atmospheric pressure)
- 0.0065: The rate at which boiling point decreases per meter of altitude increase
- Altitude: Height above sea level in meters

Altitude Boiling Point Calculator Usage Guide

Learn how to use the Altitude Boiling Point Calculator to understand how altitude affects water boiling temperature

How to Use This Calculator

  1. Enter the altitude in meters. The default value is 0 (sea level).
  2. Optionally, you can change the sea level boiling point (default is 100°C, but can be adjusted for different standards).
  3. Click the "Calculate" button to see how the boiling point changes with altitude.
  4. The calculator shows both the Celsius and Fahrenheit results.

Understanding the Principle

At higher altitudes, the atmospheric pressure is lower. Since boiling occurs when water vapor pressure equals atmospheric pressure, water boils at lower temperatures at higher altitudes. This calculator uses the standard atmospheric model where the boiling point decreases by approximately 0.0065°C per meter of altitude increase.

Practical Applications

  • Cooking at high altitudes: Adjust cooking times for foods like pasta, rice, and baked goods as boiling water is less effective.
  • Altitude sickness: Understand how boiling point changes can affect cooking and hydration at high elevations.
  • Scientific experiments: Calculate expected boiling points for experiments conducted at different altitudes.

Note: This calculator uses the standard atmospheric model and may not account for local weather conditions or variations in atmospheric pressure.
