megapascal [MPa] Unit Converter

Definition of megapascal [MPa] unit

The megapascal (MPa) is a derived SI unit of pressure equal to one million pascals. It represents one million newtons of force applied over an area of one square meter, and equals 10 bar.

History of megapascal [MPa] unit

The megapascal is based on the pascal, named after French mathematician and physicist Blaise Pascal (1623–1662), whose work included fluid pressure and vacuum studies. The pascal was adopted as the SI unit of pressure in 1971, replacing several customary and technical measures in international standards. The prefix “mega-,” from the Greek megas meaning “great” or “large,” denotes one million. As engineering and materials science developed, the megapascal became a convenient scale for expressing stresses, strengths, and pressures too large for everyday pascal notation.

Applications of megapascal [MPa] unit

Today, the megapascal is widely used in engineering, manufacturing, and science. It expresses material strength, concrete and rock pressure, hydraulic-system ratings, tire pressure testing, and fluid pressure in industrial equipment. Structural engineers may specify concrete strength in MPa, while materials datasheets report yield strength or tensile strength in MPa. One MPa equals 145.038 psi.
