Torr; Other units of pressure include: The bar (symbol: bar), defined as 100 kPa exactly. The atmosphere (symbol: atm), defined as 101.325 kPa exactly. These four pressure units are used in different settings. For example, the bar is used in meteorology to report atmospheric pressures. [7] The torr is used in high-vacuum physics and engineering ...

The current depends on the number of ions, which depends on the pressure in the gauge. Hot cathode gauges are accurate from 10 −3 Torr to 10 −10 Torr. The principle behind cold cathode version is the same, except that electrons are produced in the discharge of a high voltage. Cold cathode gauges are accurate from 10 −2 Torr to 10 −9 ...

The bar (symbol: bar) is defined as exactly 100,000 Pa. The torr (symbol: Torr) is defined as exactly 1/760 atm. The millimeter of mercury (symbol: mmHg) is defined as the product of (1) the “standard’ density of mercury at 0 °C (13.5951 g/cm 3) and (2) the “standard” acceleration of gravity g n (9.80665 m/s 2).
A msw is defined as 0.1 bar (= 10,000 Pa), is not the same as a linear metre of depth. 33.066 fsw = 1 atm [citation needed] (1 atm = 101,325 Pa / 33.066 = 3,064.326 Pa). The pressure conversion from msw to fsw is different from the length conversion: 10 msw = 32.6336 fsw, while 10 m = 32.8083 ft. [citation needed]
