You can do the reverse unit conversion from inch mercury to centitorr, or enter any two units below:
centitorr to inch of water
centitorr to millimeter water
centitorr to kilogram-force/square millimeter
centitorr to kilopond/square millimeter
centitorr to technical atmosphere
centitorr to inch water column
centitorr to decitorr
centitorr to micropascal
centitorr to torr
centitorr to centimeter of water
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widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere.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.
