How to convert megapascals to pounds per square inch
Formula: psi = MPa × 145.038
Worked example: 10 MPa → 10 × 145.038 = 1,450.38 psi

What is a megapascal?
The megapascal equals one million pascals, or 10 bar. Engineers use it for the strength of concrete and steel and for hydraulic systems: ordinary structural concrete reaches a compressive strength of 20 to 40 MPa.
What is a pound per square inch?
The pound per square inch is the US unit of pressure, about 6,894.76 pascals. Car tires are usually inflated to 30 to 35 psi, and sea-level air pressure is 14.7 psi. Gauges often read psig, the pressure above atmospheric.
