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.
About Gram per cubic centimeter (g/cm³)
A CGS-system density unit numerically equal to specific gravity relative to water at 4 °C (water = 1.000 g/cm³ by the original 1795 kilogram definition). 1 g/cm³ = 1,000 kg/m³, making the conversion between this CGS unit and the SI trivial. Widely used in geology (sedimentary rock 2.0-2.7 g/cm³, granite 2.65-2.75, basalt 2.8-3.0), crystallography and gemology (diamond 3.52 g/cm³, ruby and sapphire 4.00, opal 1.98-2.25 — density is the primary non-destructive ID method for cut gemstones), polymer chemistry (HDPE 0.94-0.97, PP 0.85-0.95, PET 1.37-1.45, PVC 1.30-1.45), and the wine, beer, and spirits industry where density is reported as specific gravity (final-gravity vs original-gravity readings drive ABV calculation). Petroleum: API gravity is defined directly from g/cm³ as °API = (141.5 / SG) − 131.5.
