How to convert
Exact conversion factors in both directions, plus a worked example.
1 mg/L = 0.001 g/L
1 g/L = 1000 mg/L
To convert milligram per liter to gram per liter, multiply by 0.001.
To convert gram per liter to milligram per liter, multiply by 1000.
Example: convert 10 mg/L to g/L
10 × 0.001 = 0.01 g/L
