How the formula works
Both milligram per milliliter and microgram 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 milliliter by 1e6 to get microgram per liter. To reverse the conversion, multiply a microgram per liter value by 1e-6 to get back to milligram per milliliter.
Frequently asked questions
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.
What is Microgram per Liter (ug/L)?
Microgram per Liter (ug/L) expresses mass in microgram per unit volume in liter, found by dividing a mass value by a volume value.
How do I convert milligram per milliliter to microgram per liter?
Multiply the milligram per milliliter value by 1e6 to get the equivalent in microgram per liter. For example, 5 mg/mL × 1e6 = 5e6 ug/L.
Is this conversion exact?
Yes. Both units are defined using fixed metric and imperial conversion constants, so the factor 1e6 is an exact, non-rounded value.
Can I convert microgram per liter back to milligram per milliliter?
Yes. Divide the microgram per liter value by 1e6, or multiply it by 1e-6, to get milligram per milliliter.
