About Kilogram per cubic meter (kg/m³)
The SI derived unit of density (ISO 80000-4 §4-2), expressing mass per unit volume. Kg/m³ is the universal scientific and engineering working unit — fluid mechanics, structural design, materials selection, chemistry, geophysics, and CFD all express density in kg/m³. Reference values: water at 4 °C is 1,000.00 kg/m³ (the historical kilogram definition), air at sea-level/15 °C is 1.225 kg/m³ (ICAO ISA), structural steel ~7,850 kg/m³, aluminum alloys ~2,700 kg/m³, normal-weight concrete ~2,400 kg/m³ (lightweight ~1,800), lead 11,340 kg/m³, tungsten 19,250 kg/m³, osmium 22,590 kg/m³ (the densest naturally-occurring element), liquid mercury 13,534 kg/m³. Materials-property databases (MatWeb, NIST MMP, ASM Handbook, Granta Selector) tabulate every alloy and plastic in kg/m³. Convert to g/cm³ by dividing by 1,000; to lb/ft³ by dividing by 16.02; to slug/ft³ by dividing by 515.4.
About Slug per cubic foot (slug/ft³)
A US engineering density unit using the 'slug' as the mass unit — the mass that accelerates at exactly 1 ft/s² when a force of 1 lbf is applied (1 slug ≈ 14.5939 kg per NIST SP 811). Slug/ft³ exists almost exclusively in US aerospace engineering, where it keeps Newton's second law F = ma dimensionally consistent in imperial units without inserting a gravitational-constant factor gc. Reference values from the ICAO International Standard Atmosphere (ISA): sea-level density ρ₀ = 0.002377 slug/ft³ (= 1.225 kg/m³), 10,000 ft pressure altitude 0.001756 slug/ft³, 30,000 ft 0.000891 slug/ft³, 60,000 ft 0.000224 slug/ft³. Aerodynamics textbooks (Anderson, Bertin & Cummings) and Federal Aviation Regulation Part 23/25 performance certification work use slug/ft³ directly in the dynamic pressure q = ½ρV², lift L = ½ρV²S·C_L, and drag D = ½ρV²S·C_D equations. NACA / NASA wind-tunnel reports historically tabulate atmospheric density in slug/ft³. 1 slug/ft³ ≈ 515.38 kg/m³.
