Inches of mercury to Kilopascals converter

To convert inches of mercury to kilopascals, enter the value in the first field. The result in kilopascals is calculated automatically using the exact conversion factor.

1 inHg = 3.386388640341 kPa
1 kPa ≈ 0.29529983301 inHg

Formula: kPa = inHg × 3.386388640341
inHg ≈ kPa × 0.29529983301

Definitions: 1 inHg = 25.4 mmHg; 1 kPa = 1000 Pa

The inch of mercury (inHg) is the pressure at the base of a one-inch column of mercury. It is used in the United States for barometric pressure in weather reports and for altimeter settings in aviation, where standard sea-level pressure is 29.92 inHg.

The kilopascal (kPa) is 1,000 pascals. It is used for tire pressure in many countries, for weather reports in Canada, and for the pressure ratings of gas cylinders, pipes and containers.
