∙ 15y agoPSI is an acronym for pounds per square inch a measure of pressure. The "real" term in most applications is "psig" or pounds per square inch gauge, which indicates that the pressure reading shows the pressure above atmospheric pressure (measured in psia - pounds per square inch absolute).
Pressure readings are also given in inches of mecury, Pascals, and kilopascals
Typical pressure readings:
* Atmospheric pressure: 14.7 psia, 760 mm Hg * Auto Tire pressure: 30 psig (43.7 psia) * Racing bike tires: 80 psig
