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 Milligrams per cubic metre
The milligram per cubic metre (mg/m³) equals 10⁻⁶ kg/m³, the reference unit for industrial occupational exposure limits (OELs). NIOSH REL for respirable crystalline silica is 0.05 mg/m³; OSHA PEL for Portland cement 15 mg/m³; ACGIH TLV for calcium carbonate dust 10 mg/m³. Numerically equal to µg/L, bridging airborne and aqueous analysis. 1 mg/m³ = 10⁻⁶ kg/m³ = 1 µg/L.
