In terms of gas pressure, what does psi stand for?

Psi stands for "pounds per square inch," which is a unit of pressure commonly used to measure the pressure of gases and fluids. It quantifies the amount of force exerted on a surface area of one square inch. This unit is particularly important in various fields, including veterinary anesthesia, where understanding gas pressures in systems such as oxygen tanks and other gas delivery mechanisms is crucial for the safe and effective administration of anesthesia to animals. The correct representation emphasizes both the force (in pounds) applied over a specific area (in square inches), which is essential for accurately gauging pressure in medical and veterinary settings.
