About these units
Megapascals (MPa): A megapascal is 1,000,000 Pa, used for material strength and high-pressure systems.
PSI (psi): Pounds per square inch (psi) is used for tyre pressure, compressors and hydraulics in the US.
Frequently asked questions
How many PSI are in 1 megapascal?
1 megapascal (MPa) equals 145.0377377 PSI.
How do I convert MPa to psi?
Multiply the value in megapascals by 145.0377377. For example, 5 MPa × 145.0377377 = 725.1886887 psi.
How do I convert PSI back to megapascals?
Multiply by 0.006894757293 (or divide by 145.0377377). 1 psi = 0.006894757293 MPa.
What is a megapascal?
A megapascal is 1,000,000 Pa, used for material strength and high-pressure systems.
Conversion factors come from exact international definitions (NIST SP 811, BIPM) where they exist. Results show up to 10 significant digits. Need every pressure unit at once? Use the Pressure Converter.
