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 Bar to MPa

1 bar = 0.1 MPa

MPa = Bar × 0.1

Example: 189 bar × 0.1 = 18.9 MPa

Reverse Conversion

To convert MPa back to bar:

  • Remember, 1 MPa equals 10 bar.
  • To convert 18.9 MPa to bar, multiply 18.9 x 10, resulting in 189 bar.

189 bar is also equal to:

  • 1.89 × 107 pascal
  • 18900 kPa
  • 2741.2 psi
About these units

Bar: Metric pressure unit equal to exactly 100,000 pascals.

MPa: SI-derived pressure unit equal to 1,000,000 pascals (10⁶ Pa).
