How the conversion works
Multiply by 145.0377377 to go from megapascal to pound per square inch, or divide by it to go back. Every conversion on this site routes through the SI value (Pa) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? pound per square inch to megapascal: 1 psi = 0.006894757293 MPa.
