What is 3000 psi in MPa?

3000 ÷ 145.038 = 20.68 MPa — a common hydraulic system pressure.

How is MPa used in concrete?

Concrete compressive strength is specified in MPa in metric countries (e.g., C25/30 means 25 MPa characteristic strength) and in psi in the US (e.g., 3,500 psi ≈ 24.1 MPa).

What is 1 MPa in bar?

1 MPa = 10 bar exactly (since 1 bar = 100 kPa = 0.1 MPa). So 10 MPa = 100 bar, a common target for high-pressure industrial systems.

Megapascals to PSI Converter

1 MPa = 145.038 psi. Used for concrete strength (20–50 MPa), hydraulic systems, and steel yield stress.

Formula

psi = MPa × 145.038

Worked example

Hydraulic cylinder rated at 20 MPa: 20 × 145.038 = 2,900.76 psi.

Unit definitions

Megapascal (MPa)

The megapascal (MPa) = 1,000,000 Pa = 1,000 kPa. Used for high-pressure systems: hydraulics, concrete strength, material tensile strength.

PSI (psi)

PSI (pounds per square inch) is the US standard for pressure. 1 psi = 6,894.757 Pa. High pressures in US engineering are often in hundreds or thousands of psi.

Common use cases

Hydraulic press and cylinder ratings
Concrete compressive strength (MPa in metric countries, psi in the US)
Material yield strength specifications
High-pressure industrial equipment
