How to Convert MPa to Bar

1 MPa = 10 bar

Bar = MPa × 10

Example: 840 MPa × 10 = 8400 bar

Reverse Conversion

To convert bar back to MPa:

  • Remember, 1 bar equals 0.1 MPa.
  • To convert 8400 bar to MPa, multiply 8400 x 0.1, resulting in 840 MPa.

840 MPa is also equal to:

  • 8.4 × 108 pascal
  • 840000 kPa
  • 121830 psi
About these units

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

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