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.
