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

centihg to megapascal

centihg to picobar

centihg to centimeter of water

centihg to zeptopascal

centihg to foot of air

centihg to femtobar

centihg to inch of mercury

centihg to millibar

centihg to millimeter water

centihg to meter of air

The SI prefix "centi" represents a factor of
10^{-2}, or in exponential notation, 1E-2.

So 1 centihg = 10^{-2} hg.

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widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere.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