**Definitions:**

**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.

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

## How to Convert Bars to Atmospheres

*Example: How many Atmospheres are equivalent to 6.47 Bars?*

As;

1 Bars = 0.987167 Atmospheres

6.47 Bars = Y Atmospheres

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

Y equals 6.47 times 0.987167 over 1

(i.e.) Y = 6.47 * 0.987167 / 1 = 6.38697049 Atmospheres

Answer is: 6.38697049 Atmospheres are equivalent to 6.47 Bars.
