Illustration of standard atmospheric pressure
14.5 psi (100 kPa) is comparable to standard atmospheric pressure at sea level (101.325 kPa).

Did you know? Standard atmosphere (1 atm) is 101.325 kPa.

Sea-level atmospheric pressure is 101.325 kPa = 14.696 psi = 760 mmHg = 1 atm exactly.

How to Convert Mbar to Pascal

1 mbar = 100 pascals

Pascal = Mbar × 100

Example: 1003 mbar × 100 = 100300 Pa

Reverse Conversion

To convert pascals back to mbar:

  • Remember, 1 pascal equals 0.01 mbar.
  • To convert 100300 Pa to mbar, multiply 100300 x 0.01, resulting in 1003 mbar.

1003 mbar is also equal to:

  • 100.3 kPa
  • 1.003 bar
  • 14.547 psi
About these units

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

Pascal: SI derived unit of pressure equal to one newton per square meter (N/m²).
