Torr (Torr) to Megapascals (MPa) Conversion
Torr
The torr is a unit of pressure named after Evangelista Torricelli, the Italian physicist who invented the mercury barometer in 1643. One torr is defined as exactly 1/760 of a standard atmosphere (approximately 133.322 Pa). Numerically nearly identical to the millimetre of mercury (mmHg), it differs by less than 0.000015%. The torr is used in vacuum science and engineering: rough vacuum is 1–100 torr, fine vacuum 10⁻³–1 torr, and ultra-high vacuum below 10⁻⁹ torr.
Megapascals
The megapascal (MPa) is a unit of pressure equal to exactly 1,000,000 pascals (10⁶ Pa) and is the standard unit for expressing material strength, hydraulic system pressure, and structural loading in engineering. The tensile strength of structural steel is approximately 400–600 MPa; high-strength carbon fibre composites can exceed 3,500 MPa. Hydraulic systems in heavy machinery operate at 20–70 MPa. In geology, lithostatic pressure in the Earth's crust is measured in MPa and GPa.
