Quick Answer:
1 megapascal = 145.038 PSI. To convert megapascals to PSI, multiply the megapascal value by 145.038.
Megapascals and PSI are the primary pressure units for industrial hydraulics, materials testing, and automotive systems.
Detailed Overview: Megapascals to PSI
A megapascal (MPa) is 1,000,000 pascals. PSI (pounds per square inch) is an imperial pressure unit. 1 MPa = 145.038 PSI. 1 PSI = 0.00689476 MPa. Multiply MPa by 145.038 for PSI. Multiply PSI by 0.00689476 for MPa. Used in hydraulic systems, materials testing, and automotive engineering.
Conversion Reference Table
1 MPa = 145.038 PSI, 5 MPa = 725.189 PSI, 10 MPa = 1450.38 PSI, 20 MPa = 2900.75 PSI, 50 MPa = 7251.89 PSI, 100 MPa = 14503.8 PSI
Practical Calculation Example
Convert 25 MPa: PSI = 25 × 145.038 = 3,625.95 PSI. Reverse: 3,000 PSI = 3,000 × 0.00689476 = 20.68 MPa
Key Takeaways
1 MPa = 145.038 PSI. Multiply MPa by 145.038 for PSI. Multiply PSI by 0.00689476 for MPa.
THE AUTORANK Editorial Note: In materials testing, MPa is standard for tensile strength, but US reports often convert to PSI, so verify the unit before comparing.
