Megapascal (MPa)

The megapascal is a x1000000 multiple of the pascal unit which is the SI unit for pressure. 1 megapascal equals 1,000,000 pascals.

Primarily used for higher range pressure measurement due to its larger value (e.g. 1 MPa = 10 bar), the MPa is mainly used to describe the pressure ranges and ratings of hydraulic systems. Despite the convenience of using megapascal pressure units to limit the number of digits used on dial gauges and readouts, the bar and the psi pressure unit are still more commonly used for describing hydraulic pressures.
