Pascals to Atmospheres converter

To convert pascals to atmospheres, enter the value in the first field. The result in atmospheres is calculated automatically using the exact conversion factor.

1 Pa ≈ 9.86923266716 × 10^-6 atm
1 atm = 101325 Pa

Formula: atm ≈ Pa × 9.86923266716 × 10^-6
Pa = atm × 101325

Definitions: 1 atm = 101325 Pa

The pascal (Pa) is the SI unit of pressure, one newton per square meter. It is a very small unit, so everyday pressures are usually given in kilopascals or hectopascals, but the pascal is the base of physics, acoustics and engineering formulas.

The standard atmosphere (atm) is exactly 101,325 pascals, the average air pressure at sea level. It is a reference pressure in chemistry and physics and is used to express high pressures as multiples of atmospheric pressure.
