How to Convert Mbar to Bar

1 mbar = 0.001 bar

Bar = Mbar × 0.001

Example: 310 mbar × 0.001 = 0.31 bar

Reverse Conversion

To convert bar back to mbar:

  • Remember, 1 bar equals 1000 mbar.
  • To convert 0.31 bar to mbar, multiply 0.31 x 1000, resulting in 310 mbar.

310 mbar is also equal to:

  • 31000 pascal
  • 31 kPa
  • 4.4962 psi
About these units

Mbar: Metric pressure unit equal to one-thousandth of a bar (0.001 bar) or 100 pascals.

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