Beyond the calculator above, it helps to understand what these two units actually represent and where you will run into them in everyday life.
Step-by-step example — Convert 1 MPa to psi:
A Megapascal (MPa) equals 1,000,000 pascals, used for rating the strength of materials like concrete and steel.
PSI (pounds per square inch) is the imperial pressure unit used throughout the US for everyday pressure measurement.
The formula is: PSI = Megapascal x 145.03768079. Multiply any Megapascal value by 145.03768079 to get the equivalent in PSI.
1 MPa = 145.03768079 psi.
1 psi = 0.00689475999997476 MPa.
Megapascal is bigger than PSI. 1 Megapascal = 145.03768079 psi.
5 MPa = 725.1884039 psi.
50 psi = 0.344738 MPa.
1 MPa equals about 145 PSI, so international specs written in MPa often need converting for US-based standards written in PSI.
