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.
About Micrograms per litre
The microgram per litre (µg/L) equals 10⁻⁶ kg/m³, numerically equal to mg/m³, and the standard unit for trace-level water quality. EPA maximum contaminant level for arsenic is 10 µg/L; WHO guideline for lead in drinking water is 10 µg/L; pharmaceutical water-for-injection requires total organic carbon below 500 µg/L. 1 µg/L = 10⁻⁶ kg/m³ = 1 mg/m³ = 1 ppb (mass) in dilute aqueous solutions.
