About the units

What is a kilopascal?

A kilopascal (kPa) is 1,000 pascals. Tire pressures in many countries and weather reports in Canada use kilopascals; standard atmosphere is 101.325 kPa.

What is a pound per square inch?

PSI (pound-force per square inch) is the US customary pressure unit, about 6,894.76 Pa. US tire pressures (typically 30–35 psi) and plumbing systems use psi.
