Frequently Asked Questions
What is the relationship between MPa and bar?
1 MPa = 10 bar exactly. This makes MPa convenient: 20 MPa = 200 bar.
How do I convert PSI to MPa?
Divide PSI by 145.038. For quick estimates, divide PSI by 145. 10,000 psi ≈ 69 MPa.
What pressures are typical in MPa?
Car hydraulic brakes: 5–10 MPa. Industrial hydraulic systems: 20–35 MPa. High-pressure water jetting: 400+ MPa. Concrete compressive strength: 20–60 MPa.
