About Pounds per cubic inch

The pound per cubic inch (lb/in³) equals ≈27 679.9 kg/m³, the standard US customary unit for engineering material density. Mechanical engineering handbooks list metals in lb/in³: steel 0.284, aluminium 0.098, copper 0.324, tungsten 0.697, lead 0.410. FEA software (ANSYS, Nastran) configured with US unit sets reads material density as lb/in³. 1 lb/in³ = 1728 lb/ft³ = 16 oz/in³ ≈27 679.9 kg/m³.

About Kilograms per litre

The kilogram per litre (kg/L) equals 1000 kg/m³, numerically identical to g/cm³ and t/m³, and preferred in industrial process engineering and chemical logistics. Dense liquids appear on safety data sheets in kg/L: sulfuric acid 1.84 kg/L, mercury 13.53 kg/L, bromine 3.10 kg/L. International bulk-liquid container certification requires density in kg/L. 1 kg/L = 1000 kg/m³ = 1 g/cm³ ≈8.345 lb/gal (US).
