Conversion Definitions
Psi, pounds per square inch, is a unit measuring pressure based on the force of pounds applied over an area of one square inch, mainly used in the US for tire pressures and industrial applications. It indicates how much force is exerted in a specific area.
Kpa, kilopascal, is a metric unit of pressure where one kpa equals 1,000 pascals, representing the force of one newton applied over an area of one square meter. It is widely used worldwide for scientific and engineering pressure measurements.
