How to convert standard atmospheres to bar
To convert standard atmospheres (atm) to bar (bar), multiply the value in standard atmospheres by 1.01325.
bar = atm × 1.01325
Example: 5 atm = 5.06625 bar.
You can also type 5 atm to bar into the smart calculator, or mix units: 1 atm + 1 bar.

About the units
Standard atmosphere (atm)
Exactly 101,325 pascals, average sea-level pressure.
Bar (bar)
Exactly 100,000 pascals, close to atmospheric pressure at sea level.
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.
