Atmospheres to Megapascals Converter
How to convert atmospheres to megapascals
megapascals = atmospheres ÷ 9.86923267
To convert atmospheres to megapascals, divide the number of atmospheres by 9.86923267.
1 atm = 0.101325 MPa
Examples
- Standard sea-level atmospheric pressure: 1 atm ÷ 9.86923267 = 0.101325 MPa
- 2 atm ÷ 9.86923267 = 0.20265 MPa
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.
- Megapascal (MPa)
- A megapascal is 1,000,000 pascals, or 10 bar. It is used for hydraulic pressures and for the strength of materials such as steel and concrete.
