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.
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.
