Did you know? Scuba tank (200 bar) is 20,000 kPa.

A full scuba tank is pressurized to 200-300 bar (20,000-30,000 kPa / 2,900-4,350 psi).

How to Convert Psi to MPa

1 psi = 0.00689476 MPa

MPa = Psi × 0.00689476

Example: 3150 psi × 0.00689476 = 21.718 MPa

Reverse Conversion

To convert MPa back to psi:

  • Remember, 1 MPa equals 145.038 psi.
  • To convert 21.718 MPa to psi, multiply 21.718 x 145.038, resulting in 3150 psi.

3150 psi is also equal to:

  • 2.1718 × 107 pascal
  • 21718 kPa
  • 217.18 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).
