Millibar to millimeters of mercury Conversion
1 millibar (mbar) is equal to 0.7500615758 millimeters of mercury (mmHg).
1 mbar = 0.7500615758 mmHg
or
1 mmHg = 1.333223874 mbar
Formula
To convert a pressure from millibar (mbar) to millimeters of mercury (mmHg), divide the pressure in millibar by 1.333223874
p(mmHg) = p(mbar) / 1.333223874
Examples:
Convert 50 millibar to millimeters of mercury:
p(mmHg) = 50mbar / 1.333223874 = 37.50307879 mmHg
