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.
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.
