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 Micrograms per cubic metre
The microgram per cubic metre (µg/m³) equals 10⁻⁹ kg/m³, the standard unit for ambient air quality reporting. WHO 2021 guidelines set annual mean limits for PM2.5 at 5 µg/m³ and PM10 at 15 µg/m³; NIOSH REL for nuisance dust is 10 000 µg/m³. Urban background air typically contains 10-50 µg/m³ of total suspended particles. 1 µg/m³ = 10⁻⁹ kg/m³ = 10⁻⁶ g/m³.
