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 milliliter (g/mL)
A density unit numerically identical to g/cm³ (since 1 mL ≡ 1 cm³ exactly by SI definition). Gram per milliliter is the universal working unit in analytical chemistry, pharmacy, biology, and clinical laboratory medicine: liquid reagent specifications, drug formulation density data, USP / EP / JP / BP / IP pharmacopoeial monographs, hydrometer-based density measurement, and solution-preparation calculations (where mass-volume conversions are routine) all use g/mL. The CRC Handbook of Chemistry and Physics tabulates several thousand pure-liquid densities in g/mL at 20-25 °C. Pharmaceutical examples: glycerin 1.261 g/mL, propylene glycol 1.036 g/mL, USP-grade ethanol (96% v/v) 0.8161 g/mL at 20 °C. Lab/clinical examples: human blood 1.060 g/mL, urine 1.005-1.030 g/mL (used for diagnostic specific gravity). Convert g/mL to kg/m³ by multiplying by 1,000; to lb/gal by multiplying by 8.345.
