Conversion Definitions
psi
Psi, or pounds per square inch, measures pressure by indicating how many pounds force is exerted on one square inch of area. It is widely used in the US for tire pressures, fluid systems, and various engineering applications where pressure levels are critical.
kpa
Kilopascal, abbreviated as kpa, is a metric unit of pressure equal to 1000 pascals. It quantifies force applied over an area, used in scientific, meteorological, and industrial contexts to measure pressure and stress across different systems and environments.
