Conversion Formulas

Millibar to PSI:

PSI = mbar × 0.0145037738

Example: 1000 mbar = 1000 × 0.0145037738 = 14.504 PSI

Millibar to Atmosphere:

atm = mbar × 0.000986923267

Example: 1013.25 mbar = 1013.25 × 0.000986923267 = 1.0 atm

Millibar to Pascal:

Pa = mbar × 100

Example: 10 mbar = 10 × 100 = 1000 Pa

Millibar to mmHg:

mmHg = mbar × 0.750061683

Example: 100 mbar = 100 × 0.750061683 = 75.006 mmHg
