You can do the reverse unit conversion from inch mercury to kilopascal, or enter any two units below:

kilopascal to meter of air

kilopascal to centipascal

kilopascal to kilonewton/square meter

kilopascal to centimeter mercury

kilopascal to decibar

kilopascal to kilobar

kilopascal to barye

kilopascal to millimeter of mercury

kilopascal to picopascal

kilopascal to millihg

The SI prefix "kilo" represents a factor of
10^{3}, or in exponential notation, 1E3.

So 1 kilopascal = 10^{3} pascals.

The definition of a pascal is as follows:

The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher.

Inches of mercury or inHg is a non-SI unit for pressure. It is still widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere.

It is defined as the pressure exerted by a column of mercury of 1 inch in height at 32 °F (0 °C) at the standard acceleration of gravity.

1 inHg = 3,386.389 pascals at 0 °C.

Aircraft operating at higher altitudes (above 18,000 feet) set their barometric altimeters to a standard pressure of 29.92 inHg or 1,013.2 hPa (1 hPa = 1 mbar) regardless of the actual sea level pressure, with inches of mercury used in the U.S. and Canada. The resulting altimeter readings are known as flight levels.

Piston engine aircraft with constant-speed propellers also use inHg to measure manifold pressure, which is indicative of engine power produced.
