How to Convert MPa to Psi

1 MPa = 145.038 psi

Psi = MPa × 145.038

Example: 0.021 MPa × 145.038 = 3.0458 psi

Reverse Conversion

To convert psi back to MPa:

  • Remember, 1 psi equals 0.00689476 MPa.
  • To convert 3.0458 psi to MPa, multiply 3.0458 x 0.00689476, resulting in 0.021 MPa.

0.021 MPa is also equal to:

  • 21000 pascal
  • 21 kPa
  • 0.21 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.

Frequently Asked Questions
