About Ounces per UK gallon
The ounce per UK gallon (oz/gal UK) equals ≈6.236 kg/m³, based on the avoirdupois ounce (28.349 g) and the UK gallon (4.54609 L). Used historically in British brewing, food manufacturing, and naval fuel specifications before metric adoption. Legacy recipes and Admiralty tables still express density in oz/gal UK. 1 oz/gal (UK) ≈6.236 kg/m³ = (1/16) lb/gal (UK).
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.
