MPa is a metric (SI) unit for pressure, or force per unit area. Pa is the Pascal, which is one Newton of force applied to one square meter of area (1 N/m2). MPa is a mega-Pascal, or one million Pascals. Since atmospheric pressure is 101 000 pA, or 101 kPa(approximately 14.7 psi), this is approximately 9 atmospheres (around 150 psi).

MPa stands for megapascal, which is a unit of pressure representing one million pascals.

A pascal is the equivalent of one newton of force applied to one square meter of area (which is a fairly small amount of pressure).

To give a relative basis, 1 atmosphere of pressure (sea level pressure) is equal to 14.7 pounds per square inch (PSI).

This is equal to 101.325 kPa = 101,325 Pa.

So, 1 MPa would be approximately equal to 10 atmospheres of pressure.
