About Gram-centimeter squared (g·cm²)
A CGS mass-moment-of-inertia unit (= 10⁻⁷ kg·m²) used for very small components: instrument gyroscopes, watch escapements, precision indexing wheels, and MEMS resonators. Optical precision instruments from historical-era European manufacturers often specify rotor inertia in g·cm².
About Pound-inch squared (lb·in²)
An imperial mass-moment-of-inertia unit (1 lb·in² ≈ 2.926 × 10⁻⁴ kg·m²) used for smaller rotating components in US mechanical engineering — servo shafts, small flywheels, and engine valvetrain components where the finer resolution compared to lb·ft² helps.
