What is a kilopascal?
A kilopascal (kPa) is 1,000 pascals, the SI unit of pressure. Canada, Australia and many car manuals list tire pressure in kPa — 220 kPa is about 32 psi. Standard atmospheric pressure at sea level is 101.325 kPa.
What is PSI?
PSI (pounds per square inch) is the US unit of pressure, used for tire pressure, air compressors, water pressure and scuba tanks. One psi is about 6.895 kilopascals. Most passenger car tires run at 30–35 psi, and household water pressure is typically 40–80 psi.
