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 Grams per cubic centimetre
The gram per cubic centimetre (g/cm³) equals 1000 kg/m³, the most intuitive density unit in material science and chemistry. It equals 1 kg/L and 1 t/m³. Pure water at 4°C is 0.9998 g/cm³; aluminium 2.70 g/cm³; iron 7.87 g/cm³; gold 19.30 g/cm³; osmium 22.59 g/cm³. Polymer datasheets, mineralogy, and gemological tables routinely use g/cm³. 1 g/cm³ = 1000 kg/m³ ≈62.428 lb/ft³.
