Convert Megapascals to PSI (MPa to psi)
1 MPa = 145.037738 psi. Convert megapascals to PSI with the exact factor, a common-values table and a free converter.
Conversion factor
psi = MPa × 145.037738
1 MPa = 145.037738 psi
Multiply by 145.037738 psi to go from megapascals to PSI, or divide by it to come back. The factor and every value below are computed by the same converter that runs at /convert, so this page and the tool cannot disagree.

Frequently asked questions
How many PSI are in one megapascal?
One megapascal is 145.037738 psi, so 100 MPa is 14503.7738 psi.
What is the formula to convert megapascals to PSI?
psi = MPa × 145.037738. Multiply the value in megapascals by 145.037738 to get PSI.
How do I convert PSI back to megapascals?
MPa = psi × 0.00689475729, so 1 psi is 0.00689475729 MPa. The psi to MPa page carries the same table in that direction.
