There is a standard model of the atmosphere which is used for calibrating instruments such as aircraft altimeters. The standard sea level pressure is 1.01325 bars, or about 760 mm Hg. In a vacuum, the pressure is reduced sufficiently to facilitate whatever process the vacuum was intended to enable; in laboratories, vacuums of 1E-8 bar or lower are attainable.

What's air pressure in a vacuum? What exactly do you think a vacuum is?
