Bars to Millimeters of Mercury Converter

To convert a measurement in bars to millimeters of mercury, multiply the value by 750.061576. The conversion factor comes from the relationship between both units and the pascal.

For example, to convert 5 bar to millimeters of mercury: 5 × 750.061576 = 3,750.3079 mmHg.

A bar is a metric unit of pressure equal to exactly 100,000 pascals, roughly equal to atmospheric pressure at sea level. Introduced by Norwegian meteorologist Vilhelm Bjerknes, the bar takes its name from the Greek 'baros' (weight). Although not an SI unit, it remains popular in industry, diving, and weather because it is close to one atmosphere.

Common uses of bars include: Scuba diving depth and tank pressure; Industrial hydraulics and pneumatics; European tire and automotive pressure; Weather systems (via millibars).

A millimeter of mercury (mmHg) is a unit of pressure equal to the pressure exerted by a one-millimeter-high column of mercury, about 133.32 pascals. Derived from early mercury barometers, the mmHg is nearly identical to the torr. It remains the standard unit for blood pressure and other physiological measurements in medicine worldwide.

Common uses of millimeters of mercury include: Blood pressure readings (systolic/diastolic); Intraocular and intracranial pressure; Barometric pressure in medicine; Vacuum and gas-pressure measurement.

Here are some common values converted:

1 bar = 750.061576 mmHg 5 bar = 3,750.3079 mmHg 10 bar = 7,500.6158 mmHg 50 bar = 37,503.0788 mmHg 100 bar = 75,006.1576 mmHg
