How to Convert MPa to Bar

1 MPa = 10 bar

Bar = MPa × 10

Example: 66.9 MPa × 10 = 669 bar

Reverse Conversion

To convert bar back to MPa:

  • Remember, 1 bar equals 0.1 MPa.
  • To convert 669 bar to MPa, multiply 669 x 0.1, resulting in 66.9 MPa.

66.9 MPa is also equal to:

  • 6.69 × 107 pascal
  • 66900 kPa
  • 9703 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.
