PSI stands for pounds per square inch. It is a unit of pressure widely used in the United States and other countries still on the imperial system. PSI measures the amount of force applied in pounds on an area of one square inch.
Kilopascals (kPa) are a metric unit of pressure, where one kilopascal equals 1,000 Pascals (Pa). The Pascal is the SI unit of pressure, and the kilopascal is commonly used for atmospheric pressure readings, among other applications, in countries using the metric system.
To convert PSI to kilopascals, multiply the pressure value in PSI by 6.89476. This conversion factor derives from the exact equivalence that 1 PSI = 6.89476 kPa.
There are approximately 6.89476 kilopascals in 1 pound per square inch.
The formula to convert PSI to kPa is: kPa = PSI x 6.89476
For example, if you have a pressure of 35 PSI, the equivalent pressure in kilopascals would be: kPa = 35 x 6.89476 = 241.3166 kPa
