About Pounds per US gallon
The pound per US gallon (lb/gal US) equals ≈119.826 kg/m³, the standard density unit in US petroleum refining, drilling, and petrochemical industries. Water at 60°F is 8.337 lb/gal; diesel 6.8-7.3 lb/gal; medium crude oil 7.1-8.0 lb/gal. Drilling mud weight per API RP 13B is specified in lb/gal (US) to control wellbore pressure. 1 lb/gal (US) ≈119.826 kg/m³ ≈7.481 lb/ft³.
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.
