Conversion Formula
MPa = GPa × 1000
About Gigapascals
A gigapascal (GPa) = 10⁹ Pa = 10 kbar - the extreme-pressure unit for materials science and planetary physics. Bulk moduli: fused silica 72 GPa; iron 170 GPa; diamond 442 GPa (highest known). Earth's inner core: 330-360 GPa. Jupiter's core: ~40,000-70,000 GPa. NIF laser-shocked experiments create 100-100,000 GPa to reproduce planetary interior conditions. Metallic hydrogen is predicted to form above ~500 GPa and has been tentatively observed at 400-500 GPa in diamond anvil cells. 1 GPa = 10⁹ Pa = 10 kbar.
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.
