What is concrete strength in MPa?

Residential concrete : 20-32 MPa (2,900-4,650 PSI) Footings/slabs : 20-25 MPa Foundation walls : 25-30 MPa Driveway : 25-32 MPa Commercial concrete : 30-50 MPa Floors : 30-35 MPa Beams/columns : 35-50 MPa High-strength : 50-100+ MPa High-rise buildings : 50-80 MPa Bridges : 60-100 MPa Special applications : 100-150 MPa Conversion : Divide PSI by 145 to get MPa (e.g., 3,000 PSI ≈ 21 MPa)

How do I convert MPa to bar?

Formula : bar = MPa × 10 Examples : 0.1 MPa = 1 bar 1 MPa = 10 bar 2 MPa = 20 bar 10 MPa = 100 bar 20 MPa = 200 bar (scuba tank) MPa to Bar converter →

What is a typical hydraulic system pressure?

Low pressure : 7-14 MPa (1,000-2,000 PSI) Automotive power steering : 8-12 MPa Light hydraulic lifts : 7-10 MPa Medium pressure : 14-21 MPa (2,000-3,000 PSI) Construction equipment : 20-25 MPa Agricultural machinery : 14-20 MPa Automotive brakes : 10-15 MPa High pressure : 21-35 MPa (3,000-5,000 PSI) Industrial presses : 25-35 MPa Heavy construction : 30-35 MPa Excavators : 30-35 MPa Very high pressure : >35 MPa (>5,000 PSI) Hydraulic jacks : 50-70 MPa Specialized industrial : 70-100 MPa

Why use MPa instead of PSI for material strength?

SI standard : International engineering uses MPa universally Simpler numbers : 400 MPa vs 58,000 PSI Scientific : Consistent with stress calculations (force/area in N/m²) Global : Specifications understood worldwide Conversion : PSI ÷ 145 ≈ MPa (or PSI × 0.00689 = MPa) Example : Steel yield strength As MPa : 250-400 MPa (easy) As PSI : 36,000-58,000 PSI (unwieldy)
