WebTorr vacuum pressure unit One torr (symbol: Torr) is approximately equal to one millimeter of mercury in a manometer at 0 °C. The unit micron can be found in the vacuum industry and its derived from the unit torr where one milliTorr is equal to one micron. WebVacuum gauge is measured from ambient air pressure in the negative direction. So for example at ambient air pressure the vacuum reading is 0 bar gauge and if a suction pressure of 0.25 bar is applied, the vacuum reading will be -0.25 bar gauge. Vacuum absolute is measured from a perfect vacuum in the positive direction. sonic 85 pc game 666
