About Converting Nanograms per Milliliter to Centigrams per Cubic Millimeter
Nanogram per Milliliter and Centigram per Cubic Millimeter 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
centigrams per cubic millimeter = nanograms per milliliter × 1e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per milliliter equals 0.000001 base units, and 1 centigram per cubic millimeter equals 10000 base units, so dividing one by the other gives the direct nanogram per milliliter-to-centigram per cubic millimeter factor of 1e-10.
Simple example
1 ng/mL × 1e-10 = 1e-10 cg/mm3
1 nanogram per milliliter = 1e-10 centigrams per cubic millimeter.
Real-world example
1,000 ng/mL × 1e-10 = 1e-7 cg/mm3
1,000 nanograms per milliliter = 1e-7 centigrams per cubic millimeter.
Conversion table

Reverse conversion: Centigram per Cubic Millimeter to Nanogram per Milliliter
1e-10 cg/mm3 × 10000000000 = 1 ng/mL
1e-10 centigrams per cubic millimeter = 1 nanograms per milliliter.
nanograms per milliliter = centigrams per cubic millimeter × 10000000000

Frequently asked questions
How many centigrams per cubic millimeter are in 1 nanogram per milliliter?
1 nanogram per milliliter equals 1e-10 centigrams per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per milliliter to centigram per cubic millimeter?
Multiply the nanogram per milliliter value by 1e-10. The converter above does this instantly to whatever precision you set.
How do I convert centigram per cubic millimeter back to nanogram per milliliter?
Use the reverse factor: 1 centigram per cubic millimeter equals 10,000,000,000 nanograms per milliliter. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per milliliter?
Nanogram per Milliliter (ng/mL) is a unit of density.
What is a centigram per cubic millimeter?
Centigram per Cubic Millimeter (cg/mm3) is a unit of density.
Is the nanogram per milliliter to centigram per cubic millimeter conversion exact?
Yes. Both nanogram per milliliter and centigram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 1e-10 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.
