PSI stands for?

Explanation:
Pressure is the amount of force acting on a given area. PSI means pounds-force per square inch. This unit is widely used in hydraulics and tool gauges because inches are a convenient size for many components in US practice, so pressure is expressed as how many pounds of force are applied to each square inch of area. If you used square meters, you’d be in the metric realm and would use pascals or kilopascals instead; using square centimeters would map to a different, less common scale for this context. So, pounds per square inch is the correct interpretation of PSI.
