What Does PSIA Stand For?
PSIA stands for Pound Per Square Inch Absolute
PSIA, or Pound Per Square Inch Absolute, is a unit of pressure measurement that represents the absolute pressure exerted by a fluid, accounting for the atmospheric pressure. Unlike gauge pressure, which measures pressure relative to atmospheric pressure, PSIA provides a more accurate representation by including atmospheric pressure in its measurement. It is commonly used in various scientific and engineering applications to ensure precise calculations and analyses in fluid dynamics and related fields.
