About Kilograms per cubic metre
The kilogram per cubic metre (kg/m³) is the SI coherent derived unit of density. Air at standard sea level is ≈1.225 kg/m³; fresh water at 4°C is ≈999.97 kg/m³; liquid mercury is 13 534 kg/m³; osmium (densest stable element) is 22 590 kg/m³. Used in the continuity equation, Bernoulli's principle, and all SI-based fluid dynamics calculations. 1 kg/m³ = 1 g/L ≈0.06243 lb/ft³.
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.
