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 Pound per cubic inch (lb/in³)
An imperial density unit for small, high-density objects — dense metals, ammunition projectiles, precision-machined components, dense polymers, and radiation-shielding materials. Reference values per ASM Handbook and MMPDS: lead 0.4097 lb/in³, copper 0.3237, brass C260 0.308, bronze 0.318, gold 0.698 (one of the highest among engineering metals), tungsten 0.697, mild steel 0.2836, stainless 304 0.286, stainless 316 0.290, Inconel 718 0.297, titanium Ti-6Al-4V 0.160, aluminum 6061 0.0975, magnesium AZ31B 0.0639. Lb/in³ appears on US ammunition specification sheets (where bullet mass is mass-per-grain but stock-material density is lb/in³), precision-machining engineering drawings and CAM software (Mastercam, Fusion 360 with imperial-unit projects), legacy US aerospace stress reports (especially structural mass-properties tables in SwRI / NASA reports), military armor-design specifications (RHA equivalency calcs), and dense-shielding calculations for medical and industrial radiation work (depleted uranium 0.685 lb/in³, lead-glass shielding 0.21 lb/in³). Metric conversion: 1 lb/in³ ≈ 27,679.9 kg/m³ ≈ 27.68 g/cm³ — a useful 27.68 multiplier for shop conversions.
