Megapascals to Psi Converter
How to convert megapascals to psi
psi = megapascals × 145.037738
To convert megapascals to psi, multiply the number of megapascals by 145.037738.
1 MPa = 145.037738 psi
Examples
- 1 MPa × 145.037738 = 145.037738 psi
- 25 MPa × 145.037738 = 3,625.94344 psi
Good to know
One megapascal is about 145 psi. Material strengths and hydraulic pressures are given in MPa in SI specifications and in psi in US ones.
Psi means pounds-force per square inch (lbf/in²). Gauge readings (psig) are measured relative to atmospheric pressure, absolute readings (psia) relative to a vacuum; the conversion factor is the same for both.

Unit definitions
- Megapascal (MPa)
- A megapascal is 1,000,000 pascals, or 10 bar. It is used for hydraulic pressures and for the strength of materials such as steel and concrete.
- Psi
- Psi is one pound-force per square inch, about 6894.757 pascals. It is the everyday pressure unit in the United States, used for tires, compressors and plumbing.
