Insert the information in the form and the calculator will determine the absolute pressure.

What is the absolute pressure?

The absolute pressure is the pressure of having no matter inside a space or a perfect vacuum.

How to calculate absolute pressure?

To calculate absolute pressure you should use the following formula:
Pabs = Pg + Patm
where:
Pabs = absolute pressure
Pg = gauge pressure
Patm = atmospheric pressure

Why use absolute pressure?

The absolute pressure is sued in processes requiting a specific amount of pressure regardless of what happens in the atmosphere.
