General Definitions of Pressure Measurements for Pressure Cookers: PSI: In the U.S.A., pressure (in pressure cooking) is referred to and measured in Imperial measurements with pounds per square inch (psi). kPa: Pressure in the rest of the world is measured in metric in kilopascals (kPa) and bars while European manufactured pressure cookers are designed to cook at 1 bar or 100 kpa (metric pressure measurements) and that translates to 14.5 psi (this is rounded up to15 psi) but American manufactured pressure cookers are designed to reach a full 15 psi. To facilitate the writing of pressure cooker cookbooks and sharing recipes, there is an un-official standard. This standard includes the maximum operating pressure for American Pressure Cookers (15 psi) and the maximum operating pressure for most modern European Cookers (which is about 13 psi for spring-valve type cookers). The "kPa" and "psi" are just two different measures of pressure, with 1psi = 6.895kPa.
