Unit of pressure, same as millimeter of mercury.

a unit of pressure equal to 0.001316 atmosphere; named after Torricelli

760 Torr = normal atmospheric pressure 1 Torr = force required to support 1 millimeter of mercury.

A unit of pressure equal to 1 mmHg or 1/760 of an atmosphere.

a measure of vapor pressure (see below). 1 torr equals 1 mmHg.

A unit of pressure used with vacuum pumps, equal to 1mm of mercury and 133.32 Pascal's. ( 188)

An obsolete unit of pressure equal to that exerted by a column of mercury 1mm high at 0°C and standard gravity (1mm Hg); named after Evangelista Torricelli (1608-1647), the inventor of the mercury barometer. 1 Torr = 1/760 atm = 133.322 Pa.

Torr; mm Hg. Compare with barometer and pressure. A unit of pressure, defined so that 760 Torr is exactly 1 atmosphere. A Torr is equivalent to 1 mm Hg on barometer readings taken at 0°C; at other temperatures, the conversion from mm Hg to Torr is approximately p(Torr) = p(mm Hg) × (1 - 1.8×10-4t), where t is in °C.

A unit of pressure equal to 1/760th of a standard atmosphere.

the pressure exerted by 1mm of mercury, Hg. Standard atmospheric pressure is 760 torr.

A unit of measure of pressure / vacuum equal to one millimeter of Hg (mercury).

Vacuum level with a scale of 0 to 760 torr with 760 being equal to atmospheric pressure at sea level - often used to refer to vacuum level deeper than 28" - same as mm Hg see heat transfer coefficient

A unit of pressure, being the pressure necessary to support a column of mercury one millimeter high at 0Â° C and standard gravity, equal to 1333.2 microbars. We use this to measure the level of vacuum in our PVD coating vessels.

unit of measurement equal to 1 mm of Hg; commonly used for specifying vacuum pressure levels.

The torr (symbol: Torr) or millimeter of mercury (mmHg) is a non-SI unit of pressure. It is the atmospheric pressure that supports a column of mercury 1 millimeter high. The unit is named after Evangelista Torricelli, Italian physicist and mathematician, for his discovery of the principle of the barometer in 1643.
