Calculation Results

Enter an altitude to see the boiling point.

Calculation Formula

Boiling Point = 100°C - (0.0065 × Altitude)

Where:
- 100°C is the boiling point of water at sea level
- 0.0065 is the rate of temperature decrease per meter of altitude
- Altitude is the height above sea level in meters

Learn how to use the Altitude Boiling Point Calculator and understand the relationship between altitude and boiling point

How to Use This Calculator

  1. Enter the altitude in meters in the input field.
  2. Click the "Calculate" button to compute the boiling point.
  3. The calculator will display the boiling point in degrees Celsius.
  4. You can reset the form by clicking the "Reset" button.

Understanding the Relationship Between Altitude and Boiling Point

The boiling point of water decreases as altitude increases. This is because atmospheric pressure decreases with altitude, which reduces the amount of pressure needed to turn water into vapor. At sea level, where atmospheric pressure is highest, water boils at 100°C (212°F). For every meter you increase in altitude, the boiling point of water decreases by approximately 0.0065°C.

Practical Applications

Understanding boiling point at different altitudes is important for various applications:

  • Cooking at high altitudes (pasta may take longer to cook, and water may not reach 100°C)
  • Weather forecasting
  • Chemical engineering processes
  • High-altitude baking and cooking

Example Calculation

For example, if you are at an altitude of 1,000 meters:

Boiling Point = 100°C - (0.0065 × 1000) = 100°C - 6.5°C = 93.5°C
