Convert Milligrams per litre to Tonnes per cubic metre
Convert Milligrams per litre (mg/L) to Tonnes per cubic metre (t/m³) instantly and accurately.
Conversion Formula
t/m³ = mg/L × 1.000000000e-6
About Milligrams per litre
The milligram per litre (mg/L) equals 10⁻³ kg/m³ and is the dominant unit in water chemistry and environmental analysis. Numerically equivalent to ppm (mass) for dilute aqueous solutions; WHO drinking-water guideline for nitrate is 50 mg/L, for fluoride 1.5 mg/L. Biological oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solids (TSS) are all reported in mg/L. 1 mg/L = 10⁻³ kg/m³ = 1 g/m³.
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.
