About Ounces per UK gallon
The ounce per UK gallon (oz/gal UK) equals ≈6.236 kg/m³, based on the avoirdupois ounce (28.349 g) and the UK gallon (4.54609 L). Used historically in British brewing, food manufacturing, and naval fuel specifications before metric adoption. Legacy recipes and Admiralty tables still express density in oz/gal UK. 1 oz/gal (UK) ≈6.236 kg/m³ = (1/16) lb/gal (UK).
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.
