How to Convert Bars to Atmospheres

Calculators can be used to convert measurements from one unit to another

To convert a bar measurement to a atmosphere measurement, multiply the pressure by the conversion ratio. One bar is equal to 0.986923 atmospheres, so use this simple formula to convert:

atmospheres = bars × 0.986923

The pressure in atmospheres is equal to the bars multiplied by 0.986923.

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

5 bar = (5 × 0.986923) = 4.934616 atm

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

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.

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.
