About Ounces per US gallon
The ounce per US gallon (oz/gal US) equals ≈7.489 kg/m³, combining the avoirdupois ounce (28.349 g) and the US liquid gallon (3.785 L). Used in US brewing and beverage production for measuring dissolved solids in wort and syrup; homebrewing grain-to-water ratios are often cited in oz/gal. 1 oz/gal (US) ≈7.489 kg/m³ = (1/16) 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.
