The torr (symbol: Torr) is a non-SI unit of pressure with the ratio of 760 to 1 standard atmosphere, chosen to be roughly equal to the fluid pressure exerted by a millimeter of mercury, i.e., a pressure of 1 Torr is approximately equal to one millimeter of mercury.
The simplest device for measuring static pressures up to about 90 pounds per square inch (62 newtons per square cm) is a U-tube manometer (shown in the figure), in which one column of a liquid in the tube is open to a region of high pressure and the other column to a region of low pressure.
