Convert Bar to Millimeters of Mercury
bar to mmHg · pressure conversion
What are bar and millimeters of mercury?
A bar is 100,000 pascals, roughly equal to atmospheric pressure at sea level. Millimeters of mercury measure pressure by the height of a mercury column, used for blood pressure. For reference: car tires run around 32 psi (220 kPa), and sea-level air pressure is about 101 kPa.
How to convert bar to millimeters of mercury
1 bar = 750.064 mmHg. To convert, multiply the number of bar by 750.064. For example, 5 bar = 3,750.32 mmHg, and 20 bar = 15,001.3 mmHg. To go the other way, multiply millimeters of mercury by 0.00133322 (since 1 mmHg = 0.00133322 bar).
