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 Pounds per UK gallon
The pound per UK gallon (lb/gal UK) equals ≈99.776 kg/m³, based on the avoirdupois pound and the UK gallon (4.54609 L). Used historically in British petroleum refining and Admiralty fuel specifications; the original UK specific-gravity tables reference lb/gal UK. Still encountered in some Commonwealth marine and aviation standards. 1 lb/gal (UK) ≈99.776 kg/m³ ≈6.228 lb/ft³.
