About Megapascals
A megapascal (MPa) = 10⁶ Pa = 10 bar - standard unit for mechanical stress, material strength, and high-pressure engineering. Structural material yield strengths: mild steel 250-550 MPa; high-strength steel to 2,000 MPa; carbon fibre composites 1,500-7,000 MPa tensile. Hydraulic press pressures 50-200 MPa. Mariana Trench floor ~110 MPa. Concrete compressive strength: 25-40 MPa (normal); up to 150 MPa (high-performance). Water-jet cutting: 200-600 MPa. Elastic moduli in FEM analysis are in MPa or GPa. 1 MPa = 10⁶ Pa = 145.0 psi.
About Millimeters of Mercury
One millimetre of mercury (mmHg) = pressure from 1 mm of mercury at 0°C and standard gravity = 133.322 Pa. Clinical medicine worldwide uses mmHg for blood pressure (normal ~120/80 mmHg) and for gas partial pressures in physiology: arterial O₂ ~95-100 mmHg; CO₂ ~40 mmHg; alveolar O₂ ~104 mmHg. Ophthalmologists measure intraocular pressure in mmHg (normal 10-21; glaucoma risk above 21). Vacuum equipment ratings are also given in mmHg. 760 mmHg = 1 atm. 1 mmHg = 133.322 Pa.
