Enter the water pressure into the calculator below to determine the boiling point.

## 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 (mmHg)

To calculate the boiling point of water, multiply the natural log of the water pressure by 49.161, then add 44.932.

## Boiling Point Definition

A boiling point measures the total temperature required for a liquid to begin boiling.
