Kilopascals to PSI Converter
Tire pressure stickers, bike pumps, and equipment manuals in metric countries read in kilopascals, but many drivers still think in psi. Converting kPa to psi is the weekly ritual of checking tires: 220 kPa is 31.9 psi, 250 kPa is 36.3. One kilopascal equals 0.145038 psi — multiply kilopascals by 0.145038. The pascal is the SI pressure unit — one newton per square meter — and the kilopascal just scales it to the sizes tires and weather actually use. The converter above gives instant two-way answers, the table covers car, bike, and trailer pressures, and the FAQs decode the numbers on your door sticker.
