About Pounds per cubic foot
The pound per cubic foot (lb/ft³) equals ≈16.018 kg/m³, widely used in US construction, soil mechanics, and insulation specifications. Softwood framing lumber averages 25-35 lb/ft³; compacted soil 90-130 lb/ft³; fresh water ≈62.43 lb/ft³; concrete 145-150 lb/ft³. ASTM standards for concrete, soil, and geotextiles routinely cite lb/ft³. 1 lb/ft³ = 0.45359237/0.028316846592 kg/m³ ≈16.018 kg/m³.
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.
