How to Convert Psi to MPa

1 psi = 0.00689476 MPa

MPa = Psi × 0.00689476

Example: 155 psi × 0.00689476 = 1.0687 MPa

Reverse Conversion

To convert MPa back to psi:

  • Remember, 1 MPa equals 145.038 psi.
  • To convert 1.0687 MPa to psi, multiply 1.0687 x 145.038, resulting in 155 psi.

155 psi is also equal to:

  • 1068700 pascal
  • 1068.7 kPa
  • 10.687 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
