In pneumatics, what property is measured by PSI?

Explanation:
PSI stands for pounds per square inch, a unit for pressure—the force exerted by the compressed air per unit area. In pneumatics, this is the key property because it tells you how much pushing force the air can apply to a piston or actuator. It isn’t a measure of how much air you have (volume), how fast the air is moving (velocity), or how thick the air is to flow (viscosity). Knowing the pressure allows you to calculate the force on a piston (force = pressure × area) and to size components and regulators accordingly.
