The SI derived unit for **pressure** is the pascal.

1 pascal is equal to 0.001 kilopascal, or 0.00029529983071445 inch of mercury.

Note that rounding errors may occur, so always check the results.

1 kilopascal to inch of mercury = 0.2953 inch of mercury

5 kilopascal to inch of mercury = 1.4765 inch of mercury

10 kilopascal to inch of mercury = 2.953 inch of mercury

20 kilopascal to inch of mercury = 5.906 inch of mercury

30 kilopascal to inch of mercury = 8.85899 inch of mercury

40 kilopascal to inch of mercury = 11.81199 inch of mercury

50 kilopascal to inch of mercury = 14.76499 inch of mercury

75 kilopascal to inch of mercury = 22.14749 inch of mercury

100 kilopascal to inch of mercury = 29.52998 inch of mercury

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

kilopascal to picopascal

kilopascal to terapascal

kilopascal to ton/square inch

kilopascal to millihg

kilopascal to millimeter of mercury

kilopascal to decipascal

kilopascal to kip/square foot

kilopascal to inch of air

kilopascal to microbar

kilopascal to hectopascal

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widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere.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.
