How to Convert Bar to MPa

1 bar = 0.1 MPa

MPa = Bar × 0.1

Example: 12.45 bar × 0.1 = 1.245 MPa

Reverse Conversion

To convert MPa back to bar:

  • Remember, 1 MPa equals 10 bar.
  • To convert 1.245 MPa to bar, multiply 1.245 x 10, resulting in 12.45 bar.

12.45 bar is also equal to:

  • 1245000 pascal
  • 1245 kPa
  • 180.57 psi
About these units

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