## What is psi?

**Psi** is a unit of pressure defined by a force of one pound on an area of one square inch. More accurately known as pound-force per square inch, other abbreviations of this unit include lbf/in² and lbf/sq in. The psi measurement is most commonly found to be used in the US and can be used to measure atmospheric pressure in certain circumstances. Above is our **pounds per square inch to bar converter**.

## What are bars?

Air pressure is measured in **bars**, a unit of gauge pressure. The bar can be divided into millibars and multiplied into kilobars depending on the scale of measurement that needs to be taken. Its use is found in the industries of meteorology, oceanography and geology. Try out our** psi to bar converter**.
