At sea level, the boiling point of water is 202°F or 100°C. However, the further from sea level you get the more the boiling point of water will change. The higher up in elevation you go, the lower the boiling point gets, while the lower you go the higher the boiling point gets.

How to Calculate Water's Boiling Point

The way you calculate the boiling point of water at a specific altitude is with this formula:

Where:
  • BP = Boiling Point

  • P = Pressure

How to use the Altitude Boiling Point Tool

Our tools are designed to be as simple and easy to use as possible. Our altitude boiling point tool is just that. The steps involved with using this tool includes:

  1. Enter the altitude you want to analyze.

  2. Hit calculate and get your answer instantly!

Why the Boiling Point of Water Changes

The boiling point of water will be affected due to the air pressure at your elevation. With a higher elevation comes less air pressure, this means it takes less energy to get water to reach the boiling point and vice versa.

When the boiling point of water goes down, it also affects the way food cooks. You will need to cook your food longer than you normally would, so adjusting your recipes for your altitude is crucial to make sure your food is thoroughly cooked and safe to eat.

Calculation Example

Let's say we are going to Denver and want to see what the boiling point temperature would be with the higher elevation. We can find that with this tool. We are going to be staying at a place that is 5,000 feet above sea level so we can enter 5,000 into the altitude field.

We can leave the unit as feet since that is accurate and then hit calculate. We get an answer of 202.37 degrees Fahrenheit, or 94.65 degrees Celsius.

Altitude & Boiling Point - Frequently Asked Questions

Yes, at higher altitudes, where the boiling point of water is lower, it can take longer to cook food thoroughly. This is because water boils at a lower temperature, providing less heat for cooking.

When cooking at high altitudes, you may need to increase cooking times and temperatures. For baking, adjustments might include increasing the amount of flour or decreasing the amount of baking powder and sugar to accommodate for faster rising due to lower air pressure.

The lower boiling point can affect the texture and flavor of food. Foods may cook differently, often requiring longer cooking times which can alter their expected taste and texture.
