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

1 pascal is equal to 0.75006167382113 centitorr, or 0.00029529983071445 inch of mercury.

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

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

centitorr to gigapascal

centitorr to kip/square inch

centitorr to inch of air

centitorr to inch of water

centitorr to ton/square foot

centitorr to poundal/square foot

centitorr to attopascal

centitorr to micropascal

centitorr to yottabar

centitorr to meter of air

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

So 1 centitorr = 10^{-2} torrs.

The definition of a torr is as follows:

The torr is a non-SI unit of pressure, named after Evangelista Torricelli. Its symbol is Torr.

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widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere.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