decitorr to zettapascal

decitorr to petabar

decitorr to newton/square millimeter

decitorr to yottabar

decitorr to kilonewton/square meter

decitorr to gigapascal

decitorr to yottapascal

decitorr to exapascal

decitorr to bar

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

So 1 decitorr = 10^{-1} 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widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere.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.
