Convert Inch of mercury to Kilopascal (inHg to Kilopascal)

Inch of mercury (inHg) and Kilopascal (Kilopascal) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert inch of mercury to kilopascal. This free online calculator tool makes it simple and easy to perform the conversion from inHg unit to the Kilopascal unit.

Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.

The inch of mercury (symbol: inHg) is a non-SI unit of pressure based on the height of a mercury column one inch high under standard gravity. It is widely used in aviation, meteorology, and vacuum measurement, particularly in the United States and Canada. Although the pascal is the SI unit of pressure, the inch of mercury remains an important unit in many industries. More information is available in the inch of mercury reference.

One inch of mercury is equal to 3,386.39 pascals, 3.38639 kilopascals, 0.0338639 bar, 0.491154 psi, and 25.4 millimeters of mercury. The inch of mercury is commonly used for barometric pressure and vacuum measurements.

The kilopascal (symbol: kPa) is an SI-derived unit of pressure equal to one thousand (10³) pascals. It is one of the most widely used pressure units in engineering, meteorology, automotive systems, construction, and scientific research. The kilopascal provides a practical scale for measuring atmospheric pressure, tire pressure, and fluid pressure. It uses the SI prefix kilo, representing a factor of one thousand.

One kilopascal is equal to 1,000 pascals, 0.01 bar, 0.001 megapascal, 0.145038 psi, and 0.00986923 standard atmosphere. The kilopascal is the preferred SI unit for many everyday and industrial pressure measurements.
