Formula: kgf/cm² = PSI × 0.07031
Multiply any psi value by 0.07031 to get kgf/cm².
Reverse: PSI = kgf/cm² × 14.22

PSI (pounds per square inch) is the primary pressure unit in the United States, UK, and other countries using Imperial measures. It equals the force of one pound-force applied over one square inch of area (6,894.76 Pa).
PSI is used for tire pressure (car: 30–35 psi, truck: 80–120 psi), blood pressure measurement in the US, boiler pressure ratings, and hydraulic system specifications in American engineering.
Interesting fact: The deepest ocean dive by a human (Victor Vescovo, 2019, 10,928 m) would have experienced about 15,900 psi of external pressure on the submersible hull.
Kilograms-force per square centimeter (kgf/cm²) is a traditional metric pressure unit that was widely used in continental Europe and Asia before SI standardization. One kgf/cm² equals approximately 98,066.5 Pa or 0.981 bar.
kgf/cm² remains common in older Japanese, Russian, Chinese, and Indian engineering standards for boiler pressure, hydraulic systems, and material strength specifications. Many legacy industrial gauges still read in kgf/cm².
Interesting fact: 1 kgf/cm² is nearly identical to 1 atm (ratio: 0.968), which is why it was historically used as a convenient engineering approximation for atmospheric pressure in many countries.
Converting psi to kgf/cm² is a common task in engineering, medicine, meteorology, and science. Different industries and countries use different pressure units — PSI in the US, bar in Europe, mmHg in medicine, and pascals in physics — making accurate conversion essential for cross-disciplinary work.
Quick reference: 5 psi = 0.3515 kgf/cm² and 10 psi = 0.7031 kgf/cm². For the reverse: 1 kgf/cm² = 14.22 psi. The exact factor is 1 psi = 0.07031 kgf/cm².
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
