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 UK gallon
The pound per UK gallon (lb/gal UK) equals ≈99.776 kg/m³, based on the avoirdupois pound and the UK gallon (4.54609 L). Used historically in British petroleum refining and Admiralty fuel specifications; the original UK specific-gravity tables reference lb/gal UK. Still encountered in some Commonwealth marine and aviation standards. 1 lb/gal (UK) ≈99.776 kg/m³ ≈6.228 lb/ft³.
