How to convert grams per liter to milligrams per liter
These are solute mass per solution volume units. Parts per million by mass cannot be assumed equal to mg/L without solution density. Percent by volume and percent by mass are also excluded.
Use x for the value in g/L, b for the intermediate value in kg/m³, and y for the result in mg/L.
mg/L = g/L ÷ 0.001
Worked examples
10 g/L ≈ 10000 mg/L
Step 1: (10 × 1) ≈ 10 kg/m³.
Step 2: 10 ÷ 0.001 ≈ 10000 mg/L.20 g/L ≈ 20000 mg/L
Step 1: (20 × 1) ≈ 20 kg/m³.
Step 2: 20 ÷ 0.001 ≈ 20000 mg/L.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Grams per liter
Grams per liter (g/L) measures concentration solution under the conventions above. The base value in kg/m³ is (x × 1), where x is the numerical value in g/L. Factors shown here are rounded for display; calculations use the stored factor.
About Milligrams per liter
Milligrams per liter (mg/L) measures concentration solution under the conventions above. The base value in kg/m³ is (x × 0.001), where x is the numerical value in mg/L. Factors shown here are rounded for display; calculations use the stored factor.
