Convert Nanograms per cubic metre to Micrograms per litre
Convert Nanograms per cubic metre (ng/m³) to Micrograms per litre (µg/L) instantly and accurately.
Conversion Formula
µg/L = ng/m³ × 1.000000000e-6
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.
About Micrograms per litre
The microgram per litre (µg/L) equals 10⁻⁶ kg/m³, numerically equal to mg/m³, and the standard unit for trace-level water quality. EPA maximum contaminant level for arsenic is 10 µg/L; WHO guideline for lead in drinking water is 10 µg/L; pharmaceutical water-for-injection requires total organic carbon below 500 µg/L. 1 µg/L = 10⁻⁶ kg/m³ = 1 mg/m³ = 1 ppb (mass) in dilute aqueous solutions.
