... 14.7 psi lower than the atmosphere. If you purchase a pressure gage at the store, the gage needle shows zero value. This is known as zero gage pressure or 14.7 psi absolute pressure. Absolute Pressure= 14.7 psi or P atmospheric + Gage pressure (measured value) Under vacuum, same terminology is appli ...
