Conversion Definitions
The following is a list of definitions relating to conversions between psi and kilopascals.
What is pounds per square inch (psi)?
Pounds per square inch (or pound-force per square inch) is a non-SI unit of Pressure. The symbol for pounds per square inch is psi or lbf/in2. There are 0.14503774 psi in a kilopascal.
What is a kilopascal (kPa)?
A kilopascal is a unit of Pressure in the International System of Units (SI). The symbol for kilopascal is kPa. There are 6.89475729 kilopascals in a psi.
Conversion Formula
Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.
The formula to convert from psi to kPa is:
kPa = psi x 6.89475729
