The Conversion Formula
To convert mmHg to bar, multiply the value by the conversion factor: 1 mmHg = 0.00133322 bar. For a worked example, suppose you need to convert 25 mmHg to bar: 25 × 0.00133322 = 0.0333305 bar. To convert in the opposite direction, divide by 0.00133322, or equivalently multiply by 750.06.
About mmHg
This unit literally measures pressure by how many millimeters it can push a column of liquid mercury up a tube. It dates back to the first barometers in the 1600s. Despite being archaic, it is the absolute global standard for measuring blood pressure. When a doctor says '120 over 80', they mean mmHg. mmHg are commonly used in Blood pressure, Meteorology, Vacuum pumps, and Laboratory physics, Medicine.
Normal systolic blood pressure is around 120 mmHg.
About bar
The bar is a metric unit, but not an SI unit. It was created to be exactly 100,000 Pascals, which makes it very close to standard atmospheric pressure (1.013 bar). This 1-to-1 approximate relationship makes 'bar' very popular in diving, hydraulics, and tire gauges outside the US. bar are commonly used in Scuba diving, Espresso machines (9 bar!), Tire pressure (Europe), and Industrial hydraulics, Weather reports (mbar).
Car tires are often inflated to 2.2 bar.
When Would You Convert mmHg to bar?
Converting between mmhg and bar is one of the most common pressure conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 mmHg = 0.00133322 bar) memorized or bookmarked can save time in professional and everyday contexts alike.
