Enter the pressure at which the water is currently experiencing into the calculator below to determine the boiling point of that water.

## Boiling Point Formula

The following equation is used to calculate the boiling point of water under a certain pressure.

bp = 49.161 * ln(p) + 44.932

- Where bp is the boiling point (F)
- p is the pressure (inHg)

As can be seen with this calculation the larger the pressure the greater the boiling point will be. It’s important to note that this equation is only for water. Other liquids will have varying boiling points based on their chemical makeup.

## Boiling Point Definition

A boiling point is a measure of the total temperature required for a liquid to begin boiling.
