Megapascals (MPa) to Millimeters of mercury (mmHg) Conversion
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.
Millimeters of mercury
The millimetre of mercury (mmHg) is a unit of pressure equal to the pressure exerted by a 1 mm column of mercury at 0 °C and standard gravity — approximately 133.322 Pa. It is the universal clinical standard for measuring blood pressure: normal adult blood pressure is approximately 120/80 mmHg (systolic/diastolic). The mmHg is also used in ophthalmology (intraocular pressure, normal ≈ 10–21 mmHg) and respiratory physiology.
