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 MPa to Psi

1 MPa = 145.038 psi

Psi = MPa × 145.038

Example: 21.05 MPa × 145.038 = 3053 psi

Reverse Conversion

To convert psi back to MPa:

  • Remember, 1 psi equals 0.00689476 MPa.
  • To convert 3053 psi to MPa, multiply 3053 x 0.00689476, resulting in 21.05 MPa.

21.05 MPa is also equal to:

  • 2.105 × 107 pascal
  • 21050 kPa
  • 210.5 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.
