Conversion Definitions
kpa
Kilopascal (kpa) is a metric unit of pressure equal to 1,000 pascals. It measures force per unit area, commonly used in meteorology, engineering, and physics to quantify pressure or stress levels in various systems.
psi
Pounds per square inch (psi) is an imperial pressure unit that measures force applied over one square inch. It is used in tire pressure, hydraulics, and other fields where pressure readings are essential for safety and performance.
