How to Convert MPa to Psi

1 MPa = 145.038 psi

Psi = MPa × 145.038

Example: 429 MPa × 145.038 = 62221 psi

Reverse Conversion

To convert psi back to MPa:

  • Remember, 1 psi equals 0.00689476 MPa.
  • To convert 62221 psi to MPa, multiply 62221 x 0.00689476, resulting in 429 MPa.

429 MPa is also equal to:

  • 4.29 × 108 pascal
  • 429000 kPa
  • 4290 bar
About these units

MPa: SI-derived pressure unit equal to 1,000,000 pascals (10⁶ Pa).

Psi: Imperial/US customary pressure unit equal to one pound-force per square inch.
