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 Grams per cubic metre
The gram per cubic metre (g/m³) equals 10⁻³ kg/m³, used for atmospheric moisture content and trace-gas emissions. Absolute humidity at 20°C is 8-15 g/m³ depending on relative humidity; ISO 13443 limits pipeline natural gas moisture to 65 mg/m³ (0.065 g/m³). Numerically equal to mg/L, simplifying conversion between air and water standards. 1 g/m³ = 10⁻³ kg/m³ = 1 mg/L.
