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 Tonnes per cubic metre
The tonne per cubic metre (t/m³) equals 1000 kg/m³, coincident with g/cm³ and kg/L. Geotechnical engineering specifies bulk unit weights in t/m³: saturated clay 1.8-2.2 t/m³, dry sand 1.4-1.7 t/m³, reinforced concrete 2.4-2.5 t/m³. Bulk-material handling uses t/m³ for conveyor and silo capacity calculations, yielding mass in tonnes directly from volume in m³. 1 t/m³ = 1000 kg/m³ = 1 g/cm³.
