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 cubic metre
The milligram per cubic metre (mg/m³) equals 10⁻⁶ kg/m³, the reference unit for industrial occupational exposure limits (OELs). NIOSH REL for respirable crystalline silica is 0.05 mg/m³; OSHA PEL for Portland cement 15 mg/m³; ACGIH TLV for calcium carbonate dust 10 mg/m³. Numerically equal to µg/L, bridging airborne and aqueous analysis. 1 mg/m³ = 10⁻⁶ kg/m³ = 1 µg/L.
