How to Convert MPa to Psi

1 MPa = 145.038 psi

Psi = MPa × 145.038

Example: 5 12 MPa × 145.038 = 797.71 psi

Reverse Conversion

To convert psi back to MPa:

  • Remember, 1 psi equals 0.00689476 MPa.
  • To convert 797.71 psi to MPa, multiply 797.71 x 0.00689476, resulting in 5 12 MPa.

5 12 MPa is also equal to:

  • 5500000 pascal
  • 5500 kPa
  • 55 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.
