Absolute pressure is the sum of gauge pressure and atmospheric pressure. For reasons we will explore later, in most cases the absolute pressure in fluids cannot be negative. Fluids push rather than pull, so the smallest absolute pressure is zero. (A negative absolute pressure is a pull)

Answer:

Absolute pressure is measured relative to a full vacuum. In contrast, pressure that is measured against atmospheric pressure (also known as barometric pressure) is called gauge pressure. A full vacuum has an absolute pressure reading of 0 PSIA and average barometric pressure at sea level is ~14.7 PSIA.

When measuring gauge pressure, current atmospheric pressure is the baseline and is therefore read as 0 PSIG. Any pressure readings taken by a transducer will be relative to that reference, which can change with variations in temperature or altitude. Full vacuum is -14.7 PSIG; or in terms of vacuum pressure, it can also be rendered as +14.7 PSIV.
