MPa is a unit of pressure and mechanical stress commonly used in engineering and materials science.
The Pascal unit is named after French scientist Blaise Pascal, who made fundamental contributions to fluid pressure and hydraulics in the 17th century.
MPa = Megapascal
MPa is used wherever high pressures or mechanical stresses are involved:
GPa = Gigapascal = 1,000 MPa = 10⁹ Pa. It is used for extremely hard materials like diamond (which has a hardness of ~90 GPa) and the Earth's mantle pressure.
