Homonym: PSI (Pounds)
PSI, or pounds per square inch, is a unit of pressure commonly used in various fields, including engineering and meteorology. It measures the force exerted by one pound of weight on an area of one square inch. This unit helps quantify how much pressure is applied in different situations, such as in tire inflation or hydraulic systems.
In addition to PSI, other pressure units include atmospheres and bar. Understanding PSI is essential for ensuring safety and efficiency in many applications, from maintaining proper tire pressure in vehicles to monitoring pressure in industrial equipment.
