How to convert pounds per square inch to kilopascals
Formula: kPa = psi × 6.89476
Worked example: 32 psi → 32 × 6.89476 = 220.632 kPa
Multiply psi by 6.89476 to get kilopascals. A tire at 32 psi is at 220.6 kPa, the unit printed on Canadian tire placards.

What is a pound per square inch?
The pound per square inch is the US unit of pressure, about 6,894.76 pascals. Car tires are usually inflated to 30 to 35 psi, and sea-level air pressure is 14.7 psi. Gauges often read psig, the pressure above atmospheric.
What is a kilopascal?
The kilopascal equals 1,000 pascals. Canadian and many European car manuals give tire pressures in kPa, for example 240 kPa, which is about 35 psi. It is also used in engineering and for blood pressure in some medical texts.
