How to Convert Psi to MPa

1 psi = 0.00689476 MPa

MPa = Psi × 0.00689476

Example: 165 psi × 0.00689476 = 1.1376 MPa

Reverse Conversion

To convert MPa back to psi:

  • Remember, 1 MPa equals 145.038 psi.
  • To convert 1.1376 MPa to psi, multiply 1.1376 x 145.038, resulting in 165 psi.

165 psi is also equal to:

  • 1137600 pascal
  • 1137.6 kPa
  • 11.376 bar
About these units

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

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

Frequently Asked Questions
