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.
