How the formula works
Both microgram per liter and microgram per milliliter measure the same physical quantity (mass per unit volume), so converting between them is a single multiplication. Multiply a value in microgram per liter by 0.001 to get microgram per milliliter. To reverse the conversion, multiply a microgram per milliliter value by 1000 to get back to microgram per liter.
Frequently asked questions
What is Microgram per Liter (ug/L)?
