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 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.
