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.
