Convert Micrograms per litre to Tonnes per cubic metre
Convert Micrograms per litre (µg/L) to Tonnes per cubic metre (t/m³) instantly and accurately.
Conversion Formula
t/m³ = µg/L × 1.000000000e-9
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 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.
