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 Technical Atmospheres
One technical atmosphere (at) = exactly 1 kgf/cm² = 98,066.5 Pa ≈ 0.968 standard atmospheres. The metric technical pressure unit used in pre-SI European and Japanese engineering for boilers, hydraulic cylinders, and compressed gas systems. A steam boiler at 10 at operates at 0.981 MPa; hydraulic presses are rated at 200-600 at. Still used parenthetically in old German and Japanese machinery manuals and standards (DIN 1301-3 legacy). Converts simply from kgf/cm²: 1 at ≡ 1 kgf/cm². 1 at = 98,066.5 Pa.
