About Kilogram-meter squared (kg·m²)
The SI unit of mass moment of inertia (ISO 80000-4 §4-12) — the rotational analog of mass, measuring a rigid body's resistance to angular acceleration about a specified axis (τ = I·α, the rotational form of Newton's second law). kg·m² is the universal working unit in rotational dynamics, flywheel-energy-storage design, gyroscope analysis, spacecraft attitude-control system (ACS) design, automotive driveline modeling (engine + clutch + transmission + driveshafts inertias propagated through gear ratios), and CAD/CAE mass-properties output (Autodesk Inventor, SolidWorks, CATIA, NX all compute Ixx/Iyy/Izz and the off-diagonal cross-products in kg·m²). Reference values: a typical 1-meter-radius solid steel cylinder of 100 kg ≈ 50 kg·m²; a figure skater's body mass moment of inertia changes from ~8 kg·m² (arms extended) to ~2 kg·m² (arms tucked tight) demonstrating angular-momentum conservation as spin rate increases ~4× when tucked; the International Space Station has ~10⁸ kg·m² principal-axis inertia. Convert kg·m² to lb·ft² by multiplying by 23.730; to slug·ft² by multiplying by 0.7376.
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.
