Vacuum Pressures Unit Conversions Chart (Relative) Perfect vacuum or 100% vacuum is a zero reference pressure. In practice, a perfect vacuum is impossible to obtain. kPa = bar x 100; mbar = bar x 1000.
In Figure(c), atmospheric pressure can support a column of fluid of height \(h\), and so \(P_{abs}\) is less than atmospheric pressure by an amount \(h\rho g\) (the gauge pressure \(P_g\) is negative). A manometer with one side open to the atmosphere is an ideal device for measuring gauge pressures.
Positive gauge pressure is any pressure that is measured above the current atmospheric pressure. Negative gauge pressure is any pressure that is measured which is below the current atmospheric pressure.

The % of vacuum is a relative value where pressure at normal or standard atmosphere is the base value. p v% = 100% - (p v / p atm) 100% (1) where . p v% = vacuum (%) p v = absolute pressure (psia, kPa, bar ..)

Negative gauge pressure is the difference between the system vacuum pressure and atmospheric pressure. Absolute pressure is the pressure (in psia) above a perfect vacuum and is equal to atmospheric pressure less negative gauge pressure. Other vacuum units are atmospheres, torr, and micrometers.
