Conversion Formula

g/m³ = t/m³ × 1000000

About Tonnes per cubic metre

The tonne per cubic metre (t/m³) equals 1000 kg/m³, coincident with g/cm³ and kg/L. Geotechnical engineering specifies bulk unit weights in t/m³: saturated clay 1.8-2.2 t/m³, dry sand 1.4-1.7 t/m³, reinforced concrete 2.4-2.5 t/m³. Bulk-material handling uses t/m³ for conveyor and silo capacity calculations, yielding mass in tonnes directly from volume in m³. 1 t/m³ = 1000 kg/m³ = 1 g/cm³.

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.
