absolute pressure

[′ab·sə‚lüt ′presh·ər]
(physics)
The pressure above the absolute zero value of pressure that theoretically obtains in empty space or at the absolute zero of temperature, as distinguished from gage pressure.

gauge pressure

The pressure, of a gas or liquid, minus the value of atmospheric pressure.

absolute pressure

The pressure measured relative to zero pressure, or a total vacuum, as opposed to gauge pressure, which is pressure measured relative to ambient pressure. A manifold absolute pressure (MAP) gauge measures absolute pressure in a reciprocating engine.
