What are millimeters of mercury and bar?
Millimeters of mercury measure pressure by the height of a mercury column, used for blood pressure. A bar is 100,000 pascals, roughly equal to atmospheric pressure at sea level. For reference: car tires run around 32 psi (220 kPa), and sea-level air pressure is about 101 kPa.
How to convert millimeters of mercury to bar
1 mmHg = 0.00133322 bar. To convert, multiply the number of millimeters of mercury by 0.00133322. For example, 5 mmHg = 0.0066661 bar, and 20 mmHg = 0.0266644 bar. To go the other way, multiply bar by 750.064 (since 1 bar = 750.064 mmHg).
