About the units
Kilopascal (kPa)
One thousand pascals. Tire pressures outside the US are often given in kPa (220–250 kPa for a car). One kilopascal equals 1,000 pascals (Pa).
Pound per square inch (psi)
One pound-force per square inch, about 6,894.76 Pa. US tire, air-compressor and hydraulic pressures are given in psi. One pound per square inch equals 6,894.757293 pascals (Pa).
