Atmospheres to Pascals Converter
How to convert atmospheres to pascals
pascals = atmospheres × 101,325
To convert atmospheres to pascals, multiply the number of atmospheres by 101,325.
1 atm = 101,325 Pa
Examples
- Standard sea-level atmospheric pressure: 1 atm × 101,325 = 101,325 Pa
- 2 atm × 101,325 = 202,650 Pa
Good to know
This is the standard atmosphere (atm), exactly 101,325 Pa. It is not the technical atmosphere (at), which is 1 kgf/cm² or 98,066.5 Pa.

Unit definitions
- Atmosphere (atm)
- The standard atmosphere is defined as exactly 101,325 pascals, approximately the average air pressure at sea level. It is used as a reference pressure in chemistry and physics.
- Pascal (Pa)
- The pascal is the SI unit of pressure, equal to one newton per square meter. It is a small unit, so kilopascals and megapascals are more common in practice.
