About Ounces per cubic inch

The ounce per cubic inch (oz/in³) equals ≈1729.994 kg/m³, a US customary unit for dense compact materials. Precision ballistic-projectile and machined-component datasheets give density in oz/in³: structural steel ≈4.51 oz/in³, lead ≈6.55 oz/in³, gold ≈11.16 oz/in³. Also found in explosive loading-density specifications. 1 oz/in³ = (1/16) lb/in³ ≈108.12 lb/ft³ ≈1729.994 kg/m³.

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.
