Megapascal (MPa)
The megapascal is a unit of pressure, used for concrete and steel strength ratings, hydraulic systems, and material science. Its symbol is MPa.

About the megapascal
The megapascal became the standard unit for expressing material strength as engineering adopted SI units, replacing kgf/cm2 and ksi in most of the world.
In everyday use the megapascal appears in concrete and steel strength ratings, hydraulic systems, and material science. As a point of reference: structural steel typically yields at around 250 MPa.
