What is a megapascal?

Engineering high-pressure unit — 10 bar or 145 psi

Definition

The megapascal equals 1,000,000 pascals or 10 bar. Used for high-pressure engineering — hydraulic systems, material strength, concrete compression tests. 1 MPa is roughly the pressure of a 100-tonne weight on 1 m².

Common uses

  • Hydraulic system pressures
  • Concrete and steel strength specifications
  • High-pressure industrial processes

🌍 Real-world scale

Concrete compressive strength: 20–60 MPa. Hydraulic press: 30–70 MPa. Steel yield strength: 250+ MPa.

Tips

  • 1 MPa = 10 bar = 145 psi.
  • N/mm² = MPa (same unit, different notation).
  • Use MPa for material science; bar for fluid dynamics.

Common mistakes

  • Confusing MPa with MW or MJ.
  • Using 1 MPa = 100 bar — that's incorrect; it's 10 bar.
  • Mixing MPa and kPa without conversion in mixed docs.
