Conversion Definitions

kpa

Kilopascal (kpa) is a unit of pressure measurement in the metric system, where 1 kpa equals 1,000 pascals. It quantifies force per unit area, commonly used for measuring atmospheric, tire, or fluid pressures, and is part of the SI unit system.

psi

Pounds per square inch (psi) is a pressure unit expressing force in pounds applied over one square inch of area. It is widely used in the United States for measuring tire pressure, hydraulic systems, and other pressure-related applications.
