Convert Micrograms per litre to Grams per cubic metre
Convert Micrograms per litre (µg/L) to Grams per cubic metre (g/m³) instantly and accurately.
Conversion Formula
g/m³ = µg/L × 0.001
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.
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.
