Most US passenger-car tires call for 32–35 psi. A typical bicycle tire runs 50–80 psi. In kilograms-force per square centimeter, that gives you: 1 psi = 0.070307 kgf/cm², 10 psi = 0.70307 kgf/cm², 100 psi = 7.0307 kgf/cm².
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 kilogram-force per square centimeter (kgf/cm²) equals exactly 98,066.5 Pa — one kilogram-force acting on one square centimeter. It is used on older pressure gauges, tire-pressure specifications, and industrial equipment in Europe, Japan, and Latin America, close to but not equal to one bar.
