Trying to move from psi units to atm units? Use our simple and accurate pressure converter to do this psi to atm conversion! Many more converters available.

As two types of units of pressure, **atmoshperes** and **pounds per square inch** are equally as important to help measure certain pressures. While units of atm are seen to be a good comparing-point when looking at measurements from many other units of pressure, units of psi are used less commonly and only in America for everyday pressure measurements. This is our** psi to atm converter** but view our other pressure converters.

## How to use the Converter for Psi to Atm?

Above you should enter a number of pounds per square inch into the **psi to atm calculator** and click the “convert” button to be given an equivalent amount in atmospheres. For the opposite conversion, go to **convert atmospheres to pounds per square inch**.

## Formula to Convert psi – atm

To do this **psi to atm conversion** by hand, you will need to know the conversion formula used by our accurate pressure converter so we have provided it for you below. As some examples, 13 psi = 0.88 atm and 45 psi = 3.06 atm

**[number of] pounds per square inch / 14.696 = [number of] atmospheres**

## What is psi?

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

## What are atmoshperes?

Atmoshperic pressure is measured by the unit of **atmoshpere**. This is done by a piece of equipment called a barometer, commonly used in meteorology. Atmospheres measure pressure through the force of an object exerted on a surface by the weight of the air above it, or in other terms the Earth’s atmoshpere. Above is our **pound per square inch – atmosphere converter**.
