The use of the term negative pressure is only appropriate if a reference pressure is present. The reference pressure used in the current standards is the value of one bar (1 bar).The former measure of negative pressure was given in atmospheres (atm); bar has been used since 1978.Since the value of the vacuum is below the reference pressure, it is also called negative pressure.
