PSI to Kilopascals Converter
Convert PSI to kilopascals for tire pressure, scientific instrumentation, and international standards documentation. Kilopascals are the SI-preferred unit and appear in automotive specs outside the US.
Formula
Multiply PSI by 6.89476 to get kilopascals. To reverse, divide kilopascals by 6.89476 to get PSI.

About these units
Pound per Square Inch
PSI is the standard pressure unit in US industry and consumer products. It measures force per unit area using the pound-force and the square inch, both derived from the avoirdupois system.
Kilopascal
The kilopascal (1000 Pa) is the SI pressure unit at a practical scale. One kPa ≈ 0.145 PSI, making kPa measurements higher in number than PSI. Tire pressure in Canada and Australia is typically labeled in kPa.
