How the formula works
Both milligram per liter and nanogram per liter measure the same physical quantity (mass per unit volume), so converting between them is a single multiplication. Multiply a value in milligram per liter by 1e6 to get nanogram per liter. To reverse the conversion, multiply a nanogram per liter value by 1e-6 to get back to milligram per liter.
Frequently asked questions
What is Milligram per Liter (mg/L)?
