How to Convert Bar to MPa

1 bar = 0.1 MPa

MPa = Bar × 0.1

Example: 138 bar × 0.1 = 13.8 MPa

Reverse Conversion

To convert MPa back to bar:

  • Remember, 1 MPa equals 10 bar.
  • To convert 13.8 MPa to bar, multiply 13.8 x 10, resulting in 138 bar.

138 bar is also equal to:

  • 1.38 × 107 pascal
  • 13800 kPa
  • 2001.5 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).
