This Boyle’s law calculator helps you calculate the initial pressure, final pressure, initial volume, and final volume.

Simply enter any three values to find the fourth one.

For example, if you want to calculate the final volume (V2), enter the P1, V1, and P2.

In 1662, Robert A. Boyle proved that gas volume is inversely proportional to pressure at a constant temperature. Hence, it describes a gas at a constant temperature.

In other words, it describes the compression and expansion of a gas at a constant temperature.

Boyle’s law is also known as Boyle–Mariotte law and Mariotte’s law.
