How to Convert Psi to MPa

1 psi = 0.00689476 MPa

MPa = Psi × 0.00689476

Example: 8 psi × 0.00689476 = 0.055158 MPa

Reverse Conversion

To convert MPa back to psi:

  • Remember, 1 MPa equals 145.038 psi.
  • To convert 0.055158 MPa to psi, multiply 0.055158 x 145.038, resulting in 8 psi.

8 psi is also equal to:

  • 55158 pascal
  • 55.158 kPa
  • 0.55158 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).
