How the formula works
Both gram per cubic millimeter 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 gram per cubic millimeter by 1e15 to get nanogram per liter. To reverse the conversion, multiply a nanogram per liter value by 1e-15 to get back to gram per cubic millimeter.
Frequently asked questions
What is Gram per Cubic Millimeter (g/mm3)?
Gram per Cubic Millimeter (g/mm3) expresses mass in gram per unit volume in cubic millimeter, found by dividing a mass value by a volume value.
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.
How do I convert gram per cubic millimeter to nanogram per liter?
Multiply the gram per cubic millimeter value by 1e15 to get the equivalent in nanogram per liter. For example, 5 g/mm3 × 1e15 = 5e15 ng/L.
Is this conversion exact?
