Knowing where PSI and Megapascal come from makes the conversion easier to remember. Here is the context, plus a quick FAQ.
Step-by-step example — Convert 30 psi to MPa:
PSI (pounds per square inch) is the imperial pressure unit used throughout the US for everyday pressure measurement.
A Megapascal (MPa) equals 1,000,000 pascals, used for rating the strength of materials like concrete and steel.
The formula is: Megapascal = PSI x 0.00689476. Multiply any PSI value by 0.00689476 to get the equivalent in Megapascal.
1 psi = 0.00689476 MPa.
1 MPa = 145.037680789469 psi.
PSI is smaller than Megapascal. 1 Megapascal = 145.037680789469 psi.
50 psi = 0.344738 MPa.
5 MPa = 725.1884039 psi.
Most passenger car tyres are inflated to 30–35 PSI, though the exact figure depends on the vehicle — check the driver's door panel for the recommended pressure.
