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.
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.
