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 Pound per gallon (lb/gal)
A liquid-density unit (lb per US gallon, abbreviated lb/gal or ppg in oilfield jargon) heavily used in US industry. Reference values: fresh water at 60 °F is 8.345 lb/gal (the universal calibration baseline), sea water ~8.55 lb/gal, gasoline ~6.15 lb/gal, kerosene/Jet A 6.5-6.8 lb/gal, diesel 6.9-7.1 lb/gal, milk ~8.6 lb/gal. The dominant industrial use is drilling-mud density in oil and gas operations: API RP 13B and the IADC mud-handling tables specify mud weight in ppg, and the hydrostatic-pressure formula in psi/ft is mud weight × 0.052 directly. Drillers chase a mud weight just heavy enough to control pore pressure but not heavy enough to fracture the formation (the 'mud window'). Lb/gal also appears in paints/coatings (VOC compliance reporting), industrial cleaners, and beer/wort specific-gravity work (homebrew + craft-brewing). Convert: 1 lb/gal = 119.83 kg/m³ = 0.1198 g/mL.
