Absolute Pressure
In engineering literature, a term used to indicate
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.
In high-vacuum technology, pressure is understood to correspond
to absolute pressure, not gage pressure, and therefore the term
absolute pressure is rarely used.
