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 Ounces per US gallon
The ounce per US gallon (oz/gal US) equals ≈7.489 kg/m³, combining the avoirdupois ounce (28.349 g) and the US liquid gallon (3.785 L). Used in US brewing and beverage production for measuring dissolved solids in wort and syrup; homebrewing grain-to-water ratios are often cited in oz/gal. 1 oz/gal (US) ≈7.489 kg/m³ = (1/16) lb/gal (US).
