Convert Grams per litre to Milligrams per litre
Convert Grams per litre (g/L) to Milligrams per litre (mg/L) instantly and accurately.
Conversion Formula
mg/L = g/L × 1000
About Grams per litre
The gram per litre (g/L) equals 1 kg/m³, numerically identical to kg/m³ but preferred in life sciences and food technology. Blood glucose is reported in g/L in European clinical practice (normal fasting: 0.7-1.0 g/L); intravenous glucose solutions are 50 g/L (5%) or 100 g/L (10%). Fermentation engineers track biomass and substrate concentration in g/L. 1 g/L = 1 kg/m³ ≈8.345 × 10⁻³ lb/gal (US).
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.
