How to Convert Bar to MPa

1 bar = 0.1 MPa

MPa = Bar × 0.1

Example: 125 bar × 0.1 = 12.5 MPa

Reverse Conversion

To convert MPa back to bar:

  • Remember, 1 MPa equals 10 bar.
  • To convert 12.5 MPa to bar, multiply 12.5 x 10, resulting in 125 bar.

125 bar is also equal to:

About these units

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