How to convert Atmosphere to Bar

Conversion factor and calculation steps from Atmosphere (atm) to Bar (bar).

Conversion logic

Each unit is defined via the base unit (pascal (Pa)). The value is first converted to the base unit, then to the selected unit.

1 atm = 101325 Pa

1 bar = 100000 Pa

1 atm × 101325 = 101325 Pa

101325 Pa ÷ 100000 = 1.01325 bar
