How many megapascals are in 1 atmosphere?

1 atmosphere equals 0.101325 MPa.

How do I convert megapascals back to atmospheres?

Use the reverse converter: 1 megapascal equals 9.86923 atm.

Yes. It uses the exact SI/NIST definitions of each unit and shows up to 6 significant digits.

To convert atmospheres to megapascals, multiply the value by 0.101325.

MPa = atm × 0.101325

80 atm × 0.101325 = 8.11 MPa

Atmosphere (atm): Standard atmosphere: exactly 101,325 pascals, the average air pressure at sea level.
Megapascal (MPa): 1,000,000 pascals; used for material strength and hydraulic systems.
