About Slug-foot squared (slug·ft²)
A US aerospace mass-moment-of-inertia unit (1 slug·ft² ≈ 1.35582 kg·m² per NIST SP 811). Because US aerospace engineers keep Newton's second law F = m·a (and its rotational analog τ = I·α) dimensionally consistent in imperial units without inserting a gravitational-constant factor gc by using slugs as the mass unit, aircraft and missile inertia properties are reported in slug·ft² in flight-dynamics textbooks (Etkin & Reid, Stevens-Lewis-Johnson, Roskam), stability derivative tables, simulation data decks (FlightGear, X-Plane, MATLAB Aerospace Toolbox), and FAR Part 25 transport-category aircraft type-certificate data sheets. Reference values: Boeing 737 roll inertia Ixx ≈ 1.8 × 10⁶ slug·ft²; pitch inertia Iyy ≈ 1.3 × 10⁷ slug·ft²; yaw inertia Izz ≈ 1.5 × 10⁷ slug·ft². Cessna 172 Ixx ≈ 1,285 slug·ft². Convert slug·ft² to kg·m² by multiplying by 1.3558.
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.
