About Converting Nanograms per Liter to Kilograms per Cubic Centimeter
Nanogram per Liter and Kilogram per Cubic Centimeter both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
kilograms per cubic centimeter = nanograms per liter × 1e-15
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per liter equals 1e-9 base units, and 1 kilogram per cubic centimeter equals 1000000 base units, so dividing one by the other gives the direct nanogram per liter-to-kilogram per cubic centimeter factor of 1e-15.
Simple example
1 ng/L × 1e-15 = 1e-15 kg/cm3
1 nanogram per liter = 1e-15 kilograms per cubic centimeter.
Real-world example
1,000 ng/L × 1e-15 = 1e-12 kg/cm3
1,000 nanograms per liter = 1e-12 kilograms per cubic centimeter.

Frequently asked questions
How many kilograms per cubic centimeter are in 1 nanogram per liter?
1 nanogram per liter equals 1e-15 kilograms per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per liter to kilogram per cubic centimeter?
Multiply the nanogram per liter value by 1e-15. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per cubic centimeter back to nanogram per liter?
Use the reverse factor: 1 kilogram per cubic centimeter equals 1e+15 nanograms per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per liter?
Nanogram per Liter (ng/L) is a unit of density.
What is a kilogram per cubic centimeter?
Kilogram per Cubic Centimeter (kg/cm3) is a unit of density.
Is the nanogram per liter to kilogram per cubic centimeter conversion exact?
Yes. Both nanogram per liter and kilogram per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 1e-15 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
