Convert Grams per cubic metre to Nanograms per cubic metre
Convert Grams per cubic metre (g/m³) to Nanograms per cubic metre (ng/m³) instantly and accurately.
Conversion Formula
ng/m³ = g/m³ × 1000000000
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 Nanograms per cubic metre
The nanogram per cubic metre (ng/m³) equals 10⁻¹² kg/m³, the resolution floor of atmospheric radionuclide and trace-contaminant monitoring. Sr-90 fallout from nuclear testing is measured in ng/m³; EPA Method TO-14A quantifies volatile organic compounds at this level. HEPA-filtered clean-room air achieves particulate densities of 1-100 ng/m³. 1 ng/m³ = 10⁻¹² kg/m³ = 10⁻³ µg/m³.
