Conversion Formula

g/L = g/m³ × 0.001

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 Grams per litre

The gram per litre (g/L) equals 1 kg/m³, numerically identical to kg/m³ but preferred in life sciences and food technology. Blood glucose is reported in g/L in European clinical practice (normal fasting: 0.7-1.0 g/L); intravenous glucose solutions are 50 g/L (5%) or 100 g/L (10%). Fermentation engineers track biomass and substrate concentration in g/L. 1 g/L = 1 kg/m³ ≈8.345 × 10⁻³ lb/gal (US).
