Formula
pascals = inHg × 3386.39
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 InHg and Pascals
InHg (inHg): Inches of mercury, the imperial equivalent of mmHg; 1 inHg = 25.4 mmHg by definition. Common uses: US weather reports (atmospheric pressure in inches of mercury, standard sea-level pressure ≈ 29.92 inHg), US aviation altimeter settings, and some US vacuum-system contexts.
Pascals (Pa): The SI unit of pressure, defined as one newton per square meter; named for Blaise Pascal, who established fundamental principles of fluid pressure in the 17th century. Common uses: Scientific work, weather (atmospheric pressure in hectopascals or kilopascals), and engineering specifications.
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 pascals = inHg × 3386.39, 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 inHg and pascals 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.
