About Slugs per cubic foot
The slug per cubic foot (slug/ft³) equals ≈515.379 kg/m³, used in US customary dynamics where forces are in pound-force. The US Standard Atmosphere gives sea-level air density as 2.377 × 10⁻³ slug/ft³; it appears in pre-SI aerospace textbooks (NACA technical notes) and compressible flow equations. 1 slug ≈14.594 kg. 1 slug/ft³ ≈515.379 kg/m³ ≈32.174 lb/ft³.
About Milligrams per litre
The milligram per litre (mg/L) equals 10⁻³ kg/m³ and is the dominant unit in water chemistry and environmental analysis. Numerically equivalent to ppm (mass) for dilute aqueous solutions; WHO drinking-water guideline for nitrate is 50 mg/L, for fluoride 1.5 mg/L. Biological oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solids (TSS) are all reported in mg/L. 1 mg/L = 10⁻³ kg/m³ = 1 g/m³.
