About Kilogram-centimeter squared (kg·cm²)

A mass-moment-of-inertia unit equal to exactly 10⁻⁴ kg·m². Used in industry for small rotating components where typical values would fall in awkwardly-small kg·m² values: electric motor rotors (NEMA / IEC motor nameplates from Japanese and Korean manufacturers commonly list rotor inertia in kg·cm² — a typical 1 kW industrial motor rotor 100-500 kg·cm² = 0.01-0.05 kg·m²), servo and stepper-motor shafts (Yaskawa, Mitsubishi, Panasonic servo datasheets — typical 750 W AC servo ~5-15 kg·cm²), small flywheels for energy-harvest applications, gyroscope and MEMS devices, and precision indexing-wheel mechanisms in machine tools. The kg·cm² is also the dominant inertia unit in Korean and Chinese-built machinery technical documentation for export markets. Convert kg·cm² to kg·m² by dividing by 10,000; to lb·in² by dividing by 0.2926; to g·cm² by multiplying by 1,000.

About Gram-centimeter squared (g·cm²)

A CGS mass-moment-of-inertia unit equal to exactly 10⁻⁷ kg·m² = 0.1 mg·m². Used for very small precision components where SI units would produce many leading zeros: balance-wheel and escapement inertia in mechanical wristwatch movements (a typical Swiss-made automatic balance wheel has rotor inertia ~10⁻² g·cm²; this drives the resonant frequency that sets watch accuracy), instrument-grade gyroscope rotors (mechanical heading reference gyros and rate-integrating gyros in aerospace inertial-navigation systems before the MEMS transition), precision indexing wheels in optical encoders (Heidenhain, Renishaw encoder discs), MEMS resonator inertia in vibratory gyroscopes per IEEE 1431 silicon-resonator characterization, and historical-era optical precision instruments from European manufacturers (Zeiss, Leica, Carl Zeiss Jena pre-1970s) which still appear in vintage equipment overhaul references. Convert g·cm² to kg·m² by dividing by 10⁷; to lb·in² by dividing by 2,926.
