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 US gallon
The pound per US gallon (lb/gal US) equals ≈119.826 kg/m³, the standard density unit in US petroleum refining, drilling, and petrochemical industries. Water at 60°F is 8.337 lb/gal; diesel 6.8-7.3 lb/gal; medium crude oil 7.1-8.0 lb/gal. Drilling mud weight per API RP 13B is specified in lb/gal (US) to control wellbore pressure. 1 lb/gal (US) ≈119.826 kg/m³ ≈7.481 lb/ft³.
