About Converting Centigrams per Fluid ounce to Nanograms per Cubic Millimeter
Centigram per Fluid ounce and Nanogram 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
nanograms per cubic millimeter = centigrams per fluid ounce × 338.140227018
This factor comes from each unit's defined relationship to the category's base unit: 1 centigram per fluid ounce equals 0.338140227018 base units, and 1 nanogram per cubic millimeter equals 0.001 base units, so dividing one by the other gives the direct centigram per fluid ounce-to-nanogram per cubic millimeter factor of 338.140227018.
Simple example
1 cg/fl oz × 338.140227 = 338.140227 ng/mm3
1 centigram per fluid ounce = 338.140227 nanograms per cubic millimeter.
Real-world example
1,000 cg/fl oz × 338.140227 = 338,140.227 ng/mm3
1,000 centigrams per fluid ounce = 338,140.227 nanograms per cubic millimeter.

Frequently asked questions
How many nanograms per cubic millimeter are in 1 centigram per fluid ounce?
1 centigram per fluid ounce equals 338.140227 nanograms per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert centigram per fluid ounce to nanogram per cubic millimeter?
Multiply the centigram per fluid ounce value by 338.140227. The converter above does this instantly to whatever precision you set.
How do I convert nanogram per cubic millimeter back to centigram per fluid ounce?
Use the reverse factor: 1 nanogram per cubic millimeter equals 0.002957353 centigrams per fluid ounce. You can also use the swap control in the converter above to flip the direction instantly.
What is a centigram per fluid ounce?
Centigram per Fluid ounce (cg/fl oz) is a unit of density.
What is a nanogram per cubic millimeter?
Nanogram per Cubic Millimeter (ng/mm3) is a unit of density.
Is the centigram per fluid ounce to nanogram per cubic millimeter conversion exact?
Yes. Both centigram per fluid ounce and nanogram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 338.140227 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.
