Millimeters of mercury to Bars converter

To convert millimeters of mercury to bars, enter the value in the first field. The result in bars is calculated automatically using the exact conversion factor.

1 mmHg = 0.00133322387415 bar
1 bar ≈ 750.061575846 mmHg

Formula: bar = mmHg × 0.00133322387415
mmHg ≈ bar × 750.061575846

Definitions: 1 mmHg = 133.322387415 Pa; 1 bar = 100000 Pa

The millimeter of mercury (mmHg) is the pressure at the base of a one-millimeter column of mercury. It is the unit of blood pressure in medicine, for example 120/80 mmHg, and is also used for some barometric and vacuum readings.

The bar equals exactly 100,000 pascals, which is very close to atmospheric pressure at sea level. It is used for tire and gas pressure in Europe, for scuba tanks (water adds about one bar per 10 meters of depth), and in hydraulics and boilers.
