How to convert
Exact conversion factors in both directions, plus a worked example.
1 g/L = 1000 mg/L
1 mg/L = 0.001 g/L
To convert gram per liter to milligram per liter, multiply by 1000.
To convert milligram per liter to gram per liter, multiply by 0.001.
Example: convert 10 g/L to mg/L
10 × 1000 = 10000 mg/L
About these units
