Convert Bars to Megapascals
Convert Bars (bar) to Megapascals (MPa) instantly and accurately.
Conversion Formula
MPa = bar × 0.1
About Bars
A bar = exactly 100,000 Pa ≈ 0.987 atm - the world standard for industrial pressure outside North America. Hydraulic systems, pneumatic equipment, gas cylinders, dive computers, and tyre gauges in Europe and Asia use bar. Scuba diving: +1 bar per 10 m depth; at 40 m recreational limit = 5 bar absolute. European tyre pressure labels show bar alongside kPa. Industrial processes: steam at 10-50 bar; high-pressure reactors 100-300 bar; water-jet cutting 1,000-4,000 bar. 1 bar = 100,000 Pa = 14.504 psi.
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.
