How the formula works
Both nanogram per liter and milligram per milliliter measure the same physical quantity (mass per unit volume), so converting between them is a single multiplication. Multiply a value in nanogram per liter by 1e-9 to get milligram per milliliter. To reverse the conversion, multiply a milligram per milliliter value by 1e9 to get back to nanogram per liter.
Frequently asked questions
What is Nanogram per Liter (ng/L)?
Nanogram per Liter (ng/L) expresses mass in nanogram per unit volume in liter, found by dividing a mass value by a volume value.
What is Milligram per Milliliter (mg/mL)?
Milligram per Milliliter (mg/mL) expresses mass in milligram per unit volume in milliliter, found by dividing a mass value by a volume value.
How do I convert nanogram per liter to milligram per milliliter?
Multiply the nanogram per liter value by 1e-9 to get the equivalent in milligram per milliliter. For example, 5 ng/L × 1e-9 = 5e-9 mg/mL.
Is this conversion exact?
Yes. Both units are defined using fixed metric and imperial conversion constants, so the factor 1e-9 is an exact, non-rounded value.
Can I convert milligram per milliliter back to nanogram per liter?
Yes. Divide the milligram per milliliter value by 1e-9, or multiply it by 1e9, to get nanogram per liter.
