Converting from units of atm to units of psi? Make things easier by using this atmosphere to pound per square inch converter for your calculations!

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

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

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

## Formula to Convert atm – psi

To do this **atm to psi 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, 6 atm = 88.2 psi and 70 atm = 1,028.7 psi

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

## What are atmoshperes?

Atmoshperic pressure is measured by the unit of **atmoshpere **by a piece of equipment called a barometer, which is 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 **atmosphere – pound per square inch converter**.

## 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. 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. Try our **atmospheres to pounds per square inch converter**.
