About Slug-foot squared (slug·ft²)

A US aerospace mass-moment-of-inertia unit (1 slug·ft² ≈ 1.356 kg·m²). Because aerospace engineers in the US keep F=ma self-consistent by using slugs as the mass unit, aircraft and missile inertia properties are often reported in slug·ft² in flight dynamics textbooks, stability derivatives, and simulation data decks.

About Kilogram-meter squared (kg·m²)

The SI unit of mass moment of inertia — the rotational analog of mass, measuring resistance to angular acceleration. kg·m² is the universal unit in rotational dynamics (τ = Iα), flywheel energy calculations, and spacecraft attitude-control design. A figure skater's mass moment of inertia changes dramatically between arms-extended and arms-tucked postures, demonstrating angular-momentum conservation visibly.
