Kilopascals to PSI (kPa to psi) Converter
1 kilopascal equals 0.14503774 psi — multiply kilopascals by 0.14503774 to convert. One psi (pound-force per square inch) is about 6.894757 kPa, so each kilopascal is the reciprocal of that, roughly 0.145 psi.
The formula
Multiply the kilopascal value by 0.14503774 to get psi:
psi = kPa × 0.14503774
For example, 220 kPa × 0.14503774 = 31.9083 psi. To reverse, divide psi by 0.14503774 (or multiply by 6.894757).

Where this conversion is used
Tyre pressure is the classic case: many cars list recommended pressures in kPa while US gauges and pumps read in psi. The conversion also matters for compressed-air tools, bicycle tyres, plumbing systems, and industrial equipment sold across metric and imperial markets. Getting it right keeps tyres safe and machinery within spec.
FAQ
How many psi are in a kilopascal?
