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.
About Kilogram per liter (kg/L)
A density unit numerically identical to g/cm³ and g/mL (since 1 L ≡ 1,000 cm³ ≡ 1,000 mL by SI definition). Kg/L is a natural unit for industrial liquids and a working unit for fuel quality and dispensing: gasoline ~0.74 kg/L (RBOB regular at 15 °C per ASTM D4052), diesel ~0.832 kg/L, kerosene/Jet A1 0.775-0.840 kg/L (range per ASTM D1655 / DEF STAN 91-091), jet fuel JP-8 ~0.80 kg/L, residential heating oil ~0.86 kg/L, residual fuel oil (HFO) 0.95-1.01 kg/L. Aviation fuel uplift uses kg/L to convert delivered volume (liters) into mass (kilograms) for the load-and-balance manifest — fuel volume contracts at altitude/cold but the mass that matters for performance stays constant. Wine, beer, and spirits production also uses kg/L for batch yield calculations and ABV-from-density math. 1 kg/L = 1,000 kg/m³ = 8.345 lb/gal.
