How to convert bar to standard atmospheres
To convert bar (bar) to standard atmospheres (atm), divide the value in bar by 1.01325.
atm = bar ÷ 1.01325
Example: 5 bar = 4.934616334 atm.
You can also type 5 bar to atm into the smart calculator, or mix units: 1 bar + 1 atm.

About the units
Bar (bar)
Exactly 100,000 pascals, close to atmospheric pressure at sea level.
Standard atmosphere (atm)
Exactly 101,325 pascals, average sea-level pressure.
Pressure is force per unit area. The SI unit is the pascal, one newton per square meter. Tire pressures are given in psi or bar, weather in hectopascals or millibars, and blood pressure in millimeters of mercury.
