Convertisseur de Mégapascals en Torr

The megapascal (MPa) equals one million pascals and is the standard unit for high-pressure applications in structural engineering, materials testing, and hydraulic systems. Concrete strength is rated in megapascals, and steel tensile strength specifications routinely reference this unit. One megapascal equals 10 bar or approximately 145 psi, bridging metric and imperial pressure scales.

The torr is a pressure unit named after Evangelista Torricelli, equal to approximately 133.322 pascals, used primarily in vacuum physics and high-altitude research. It is nearly identical to the millimeter of mercury, with one torr defined as exactly 1/760 of a standard atmosphere. Vacuum pumps, electron microscopes, and semiconductor manufacturing equipment commonly specify operating pressures in torr.
