kPa to psi for tire pressure and gauges

Kilopascals are common on international tire labels, pressure sensors, and engineering documents. Psi is common on US gauges and consumer equipment. Converting kPa to psi helps translate metric pressure guidance into the readings many users see on pumps and gauges.

Reading rounded pressure labels

Many tire and equipment labels round kPa and psi values separately, so a printed pair may not match a calculator perfectly. Use the exact source value when precision is important.
