what is a megapascal
Megapascal (MPa) is a metric pressure unit and equals to 1 000 000 force of newton per square meter which is know as a Pascal. 1 MPa equals to 10 Bar. Because of its high pressure ratings is often used in hydraulic and simular systems.egapascal is generally used to measure the pressure of heavy machines such as hydraulic system. Since the pressure of these machines can't be measured in pascals hence megapascals is used to describe the heavy pressures. Megapascal can easily be converted in other unit of pressure.
