Pressure is force per area. 1 atm = 101.325 kPa = 14.696 psi = 760 mmHg. Bar is a metric working unit close to atmospheric pressure (1 bar = 100 kPa).
About Bar and MmHg
Bar (bar): Defined as exactly 100,000 pascals, or roughly atmospheric pressure at sea level; the name comes from the Greek baros meaning weight. Common uses: European weather reports, tire pressure in some countries (and motorcycles globally), gas cylinder pressures, and brewery/winery pressures.
MmHg (mmHg): Millimeters of mercury; the pressure exerted by a column of mercury that height; a torr is essentially identical (1 mmHg ≈ 1 torr to within 1 part in 7 million). Common uses: Blood pressure (systolic over diastolic, in mmHg), vacuum systems, barometric pressure in some medical and scientific contexts.
How the conversion works
Pressure is force per area. 1 atm = 101.325 kPa = 14.696 psi = 760 mmHg. Bar is a metric working unit close to atmospheric pressure (1 bar = 100 kPa).
The exact relationship is mmHg = bar × 7.50063755e+2, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between bar and mmHg comes up wherever pressure measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
