About Kilograms per litre

The kilogram per litre (kg/L) equals 1000 kg/m³, numerically identical to g/cm³ and t/m³, and preferred in industrial process engineering and chemical logistics. Dense liquids appear on safety data sheets in kg/L: sulfuric acid 1.84 kg/L, mercury 13.53 kg/L, bromine 3.10 kg/L. International bulk-liquid container certification requires density in kg/L. 1 kg/L = 1000 kg/m³ = 1 g/cm³ ≈8.345 lb/gal (US).

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.
