In pneumatics, what does PSI measure?

Explanation:
PSI is a measure of pressure—the pounds of force per square inch in the air of a pneumatic system. It tells you how much pushing power the compressed air can apply to a piston or actuator. It isn’t a measure of temperature, flow rate (which is about how much air moves over time), or humidity (moisture content). Knowing the system pressure helps predict actuator performance: higher PSI means more available force, within the component limits. The basic idea is that force on a piston equals pressure times the piston area, so PSI directly governs how strong the actuation will be.
