How to Convert Psi to MPa

1 psi = 0.00689476 MPa

MPa = Psi × 0.00689476

Example: 990 psi × 0.00689476 = 6.8258 MPa

Reverse Conversion

To convert MPa back to psi:

  • Remember, 1 MPa equals 145.038 psi.
  • To convert 6.8258 MPa to psi, multiply 6.8258 x 145.038, resulting in 990 psi.

990 psi is also equal to:

  • 6825800 pascal
  • 6825.8 kPa
  • 68.258 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).
