Atmospheres to Megapascals converter

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

1 atm = 0.101325 MPa
1 MPa ≈ 9.86923266716 atm

Formula: MPa = atm × 0.101325
atm ≈ MPa × 9.86923266716

Definitions: 1 atm = 101325 Pa; 1 MPa = 1000000 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 megapascal (MPa) is one million pascals, or one newton per square millimeter. It is the standard unit for material strength, hydraulic pressure and high-pressure equipment, and for stress in steel and concrete.
