Need to convert pressure from bars to atmospheres? This is a great tool to help with bar to atm pressure conversions! Simple and accurate to use, more here.

To measure pressure, you might do so with units of **atmosphere** or **bar** that are commonly found to calculate air pressures. The bar has recently been seen as a more universal and popular choice of unit, seeing that the atmosphere is beginning to be used less. Pressure is measured by any unit of force divided by any unit of area, however it is simpler to use set units of pressure instead. View our other pressure converters and use our **bar to atmosphere calculator**.

## How to use the Converter for Bars to Atmospheres?

Above, enter in the box the amount of bars you need to change and click “convert” for a **bar – atmosphere conversion** that will present a new quantity of atmospheres. To work the other way, convert atmosphere to bar.

## Formula to Convert bar – atm

Provided below is the mathematical formula used by our accurate **converter of bar – atm** that you can use yourself if you wish to do the calculation by hand. For instance, 9 bar = 8.88 atm and 40 bar = 39.48 atm

**[number of] bars / 1.01325 = [number of] atmospheres**

## What are bars?

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

## 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 **bar – atmosphere converter**.
