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 foot
The pound per cubic foot (lb/ft³) equals ≈16.018 kg/m³, widely used in US construction, soil mechanics, and insulation specifications. Softwood framing lumber averages 25-35 lb/ft³; compacted soil 90-130 lb/ft³; fresh water ≈62.43 lb/ft³; concrete 145-150 lb/ft³. ASTM standards for concrete, soil, and geotextiles routinely cite lb/ft³. 1 lb/ft³ = 0.45359237/0.028316846592 kg/m³ ≈16.018 kg/m³.
