Pascals to atm

Convert pascals to standard atmospheres quickly. One atmosphere equals 101,325 Pa — enter any pascal value to see the atm equivalent.

101325 Pa ÷ 101325 = 1.000000 atm

Result in atm

1 atm

About this calculator

The pascal (Pa) is the SI unit of pressure, and the atmosphere (atm) is a reference unit defined as exactly 101,325 Pa — roughly the air pressure at sea level. Converting between them is common in physics, chemistry, meteorology, and thermodynamics when working with gas laws and atmospheric measurements.
