Frequently Asked Questions

What is the difference between Absolute and Gauge Pressure?


Absolute pressure is zero-referenced against a perfect vacuum, so it is equal to gauge pressure plus atmospheric pressure. Gauge pressure is zero-referenced against ambient air pressure, so it is equal to absolute pressure minus atmospheric pressure.

There are several units of pressure measurement that are used based on your reference point. Some common examples of Absolute reference are Torr and psia. Some examples of Gauge reference are psig and inches of mercury (vacuum).
