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.
About Milligrams per litre
The milligram per litre (mg/L) equals 10⁻³ kg/m³ and is the dominant unit in water chemistry and environmental analysis. Numerically equivalent to ppm (mass) for dilute aqueous solutions; WHO drinking-water guideline for nitrate is 50 mg/L, for fluoride 1.5 mg/L. Biological oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solids (TSS) are all reported in mg/L. 1 mg/L = 10⁻³ kg/m³ = 1 g/m³.
