1 mpa to psi: 1 megapascal in pounds per square inch

1 MPa is about 145.038 pounds per square inch (145.038 psi).

1 MPa in pounds per square inch

145.038 psi

How it is calculated

Formula: psi = MPa × 145.0377377

1 megapascal = 145.0377377 pounds per square inch
1 × 145.0377377 = 145.03774 psi

What this means

That is 9.869 standard atmospheres (1 atm = 101.325 kPa = 14.696 psi = 1.01325 bar).
The same pressure in bar: 10 bar.
Quick estimate: 1 × 150 ≈ 150 psi (exact: 145.038 psi).
