Megapascals to Atmospheres converter

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

1 MPa ≈ 9.86923266716 atm
1 atm = 0.101325 MPa

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

Definitions: 1 MPa = 1000000 Pa; 1 atm = 101325 Pa

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.

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.
