Pascals to Atmospheres Converter
How to convert pascals to atmospheres
atmospheres = pascals ÷ 101,325
To convert pascals to atmospheres, divide the number of pascals by 101,325.
1 Pa = 0.00000986923267 atm
Examples
- Standard sea-level atmospheric pressure: 101,325 Pa ÷ 101,325 = 1 atm
- 1,000 Pa ÷ 101,325 = 0.00986923267 atm
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
- 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.
- 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.
