Convert Micrograms per litre to Kilograms per cubic metre
Convert Micrograms per litre (µg/L) to Kilograms per cubic metre (kg/m³) instantly and accurately.
Conversion Formula
kg/m³ = µg/L × 1.000000000e-6
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 Kilograms per cubic metre
The kilogram per cubic metre (kg/m³) is the SI coherent derived unit of density. Air at standard sea level is ≈1.225 kg/m³; fresh water at 4°C is ≈999.97 kg/m³; liquid mercury is 13 534 kg/m³; osmium (densest stable element) is 22 590 kg/m³. Used in the continuity equation, Bernoulli's principle, and all SI-based fluid dynamics calculations. 1 kg/m³ = 1 g/L ≈0.06243 lb/ft³.
