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.
About Pounds per cubic foot
The pound per cubic foot (lb/ft³) equals ≈16.018 kg/m³, widely used in US construction, soil mechanics, and insulation specifications. Softwood framing lumber averages 25-35 lb/ft³; compacted soil 90-130 lb/ft³; fresh water ≈62.43 lb/ft³; concrete 145-150 lb/ft³. ASTM standards for concrete, soil, and geotextiles routinely cite lb/ft³. 1 lb/ft³ = 0.45359237/0.028316846592 kg/m³ ≈16.018 kg/m³.
