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.
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.
