What Does PSI Stand For?

PSI stands for Pounds Per Square Inch Static Pressure

PSI, or Pounds Per Square Inch Static Pressure, is a unit of measurement used to quantify the pressure exerted by a fluid at rest per square inch of surface area. It is commonly applied in various fields such as hydraulics, pneumatics, and HVAC systems to assess the static pressure in systems, ensuring optimal performance and safety. The measurement is critical for understanding the behavior of liquids and gases in engineering applications, allowing for precise calculations and system designs.
