What Does PSIG Stand For?
PSIG stands for Pounds Per Square Inch Gage
PSIG, or Pounds Per Square Inch Gage, is a unit of pressure measurement that indicates the pressure of a gas or liquid relative to the ambient atmospheric pressure. It is commonly used in various industries, including engineering, manufacturing, and HVAC, to assess and monitor pressure levels in systems and equipment. Unlike absolute pressure measurements, PSIG accounts for atmospheric pressure, providing a clear understanding of the pressure exerted by a fluid in a system.
