How the formula works
Both carat per milliliter 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 carat per milliliter by 2e11 to get nanogram per liter. To reverse the conversion, multiply a nanogram per liter value by 5e-12 to get back to carat per milliliter.
Frequently asked questions
What is Carat per Milliliter (ct/mL)?
