Atmospheres to Pascals converter

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

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

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

Definitions: 1 atm = 101325 Pa

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.

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.
