The torr is a unit of measure for barometric pressure, and it is equal to 1mmHg. Barometric pressure is the same as atmospheric pressure, which is the is the force per unit area exerted on a surface by the weight of air above that surface in the atmosphere of Earth or another planet. It can be measured in mmHg (torr), atmospheres (atm), Pascals (Pa), bars, inHg (inches of mercury), and psi (pounds per square inch).

The standard atmosphere (symbol: atm) is a unit of pressure equal to 101325 Pa or 1013.25 millibars or hectopascals. It is equivalent to 760 mmHg (torr), 29.92 inHg, 14.696 psi. Source: http://en.wikipedia.org/wiki/Atmospheric_pressure
