About the pound per square inch and the kilopascal
The pound per square inch
The pound per square inch (psi) is the customary US pressure unit, derived from the avoirdupois pound-force on a square inch (≈ 6,894.76 Pa exactly). It is the standard unit on US car tire-pressure stickers, scuba gauges in the US, and most plumbing specifications.
The kilopascal
The kilopascal (kPa) equals exactly 1,000 pascals. It is the standard pressure unit in modern meteorology, engineering specs outside the US, and most non-US tire-pressure recommendations.
