About Grams per cubic metre

The gram per cubic metre (g/m³) equals 10⁻³ kg/m³, used for atmospheric moisture content and trace-gas emissions. Absolute humidity at 20°C is 8-15 g/m³ depending on relative humidity; ISO 13443 limits pipeline natural gas moisture to 65 mg/m³ (0.065 g/m³). Numerically equal to mg/L, simplifying conversion between air and water standards. 1 g/m³ = 10⁻³ kg/m³ = 1 mg/L.

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).
