## How to Convert Atmospheres to Bars

To convert an atmosphere measurement to a bar measurement, multiply the pressure by the conversion ratio. One atmosphere is equal to 1.01325 bars, so use this simple formula to convert:

The pressure in bars is equal to the atmospheres multiplied by 1.01325.

**For example,**here's how to convert 5 atmospheres to bars using the formula above.

Atmospheres and bars are both units used to measure pressure. Keep reading to learn more about each unit of measure.

## Atmospheres

The atmosphere is a reference measure of pressure equal to 101,325 pascals or 1,013,250 dynes. The atmosphere was originally defined as the pressure of 760 millimeters of mercury at standard gravity at 0 °C, but was later redefined in 1954 to be equal to 1,013,250 dynes.

Atmospheres can be abbreviated as *atm*, for example 1 atmosphere can be written as 1 atm.

## Bars

The bar is equal to 100,000 pascals, which are defined as the pressure of one newton per square meter. One bar is just less than the average atmospheric pressure.

The bar is a non-SI metric unit for pressure. Bars can be abbreviated as *bar*, for example 1 bar can be written as 1 bar.
