About Megapascal (MPa)
A metric unit of pressure equal to exactly 1,000,000 pascals (1,000 kPa), or 10 bar. Megapascals are the universal SI unit for material strength reporting in structural and mechanical engineering: concrete compressive strength (typically 20-60 MPa per ACI 318 / Eurocode 2, with ultra-high-performance concrete reaching 150-200 MPa), structural-steel yield stress (250 MPa for S275 / A36, 355 MPa for S355, up to 690 MPa for HSLA grades), aluminum tensile (6061-T6 ~310 MPa), and the fracture toughness of ceramics and polymers reported as MPa·m^½ in materials databases. Mechanical-engineering finite-element solvers (Abaqus, ANSYS, Nastran), pressure-vessel codes (ASME BPVC Section VIII, PD 5500, EN 13445), hydraulic system specifications above ~70 bar, and the civil-engineering concrete mix specs all use MPa as the working pressure/stress unit. Common conversions: 1 MPa = 10 bar = 145.04 psi = 9.869 atm.
About Millimeters of Mercury (mmHg)
A unit of pressure historically defined as the pressure exerted by a column of mercury exactly 1 millimeter tall at the standard acceleration of gravity (9.80665 m/s²) and the standard density of mercury (13,595.1 kg/m³ at 0 °C). The mmHg's contemporary definition rounds to exactly 133.322387415 Pa (NIST SP 811). Despite being non-SI, mmHg remains the international clinical standard for blood pressure measurement ("120 over 80" mmHg) per WHO and ESH guidelines, and is the default unit for intraocular pressure in ophthalmology (normal IOP 10-21 mmHg per Glaucoma Research Foundation) and intracranial pressure monitoring in neurology. Numerically the mmHg is almost identical to the torr (1 mmHg ≈ 1.0000007 torr — the difference is whether one uses the conventional density or the experimentally measured density of mercury). Barometric atmospheric pressure was historically quoted in mmHg before kPa/hPa adoption (760 mmHg = 1 atm = 101.325 kPa).
