Kg/cm² & PSI FAQ
Everything you need to know about converting between kg/cm², PSI, bar and kPa for tyres, gauges, and industrial equipment.
1 kg/cm² (kilogram-force per square centimetre) is exactly equal to 14.2233433071 PSI (pounds per square inch). In most practical settings this is rounded to 14.22 PSI, which is accurate enough for tyre pressures, gauges, and hydraulic systems.
Multiply the kg/cm² value by 14.2233. For example, 2 kg/cm² x 14.2233 equals 28.45 PSI. To go the other way, divide the PSI value by 14.2233, or multiply by 0.070307, to get kg/cm².
They are very close but not identical. 1 kg/cm² equals 0.980665 bar, while 1 bar equals 1.0197 kg/cm². For most everyday tyre and gauge readings the two units are used almost interchangeably, but engineering calculations should use the precise conversion factor.
2 kg/cm² converts to approximately 28.45 PSI. Most passenger car tyres are inflated between 2.0 and 2.5 kg/cm² (28 to 36 PSI), so this sits within the typical recommended range, though you should always check your vehicle’s specific placard for the exact figure.
Kg/cm² (also written kgf/cm²) is a metric pressure unit historically common in Japan, parts of Europe, and Asia for tyre gauges, compressors, and industrial equipment, while PSI is standard in the UK, US, and much of the English-speaking world. Imported equipment and older gauges often retain the kg/cm² scale, so a converter is useful when cross-referencing manuals.
