**Definitions:**

**Atmosphere** (abbreviation: **atm**): is a unit of standard pressure, equal to 101325 Pa, or 1.01325 bar.

**Bar** (abbreviation: **bar**): is a metric (still not approved by the International System of Units, SI) unit of pressure. It is exactly equal to 100,000 Pa and slightly lower than the current average atmospheric pressure on Earth, at sea level.

## How to Convert Atmospheres to Bars

*Example: How many Bars are equivalent to 34.92 Atmospheres?*

As;

1 Atmospheres = 1.01325 Bars

34.92 Atmospheres = Y Bars

Assuming Y is the answer, and by criss-cross principle;

Y equals 34.92 times 1.01325 over 1

(i.e.) Y = 34.92 * 1.01325 / 1 = 35.38269 Bars

Answer is: 35.38269 Bars are equivalent to 34.92 Atmospheres.
