About Converting Nanograms per Cubic foot to Centigrams per Gallon
Nanogram per Cubic foot and Centigram per Gallon 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 gallon = nanograms per cubic foot × 1.336806e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per cubic foot equals 3.531467e-11 base units, and 1 centigram per gallon equals 0.00264172052358 base units, so dividing one by the other gives the direct nanogram per cubic foot-to-centigram per gallon factor of 1.336806e-8.
Simple example
1 ng/ft3 × 1.336806e-8 = 1.336806e-8 cg/gal
1 nanogram per cubic foot = 1.336806e-8 centigrams per gallon.
Real-world example
1,000 ng/ft3 × 1.336806e-8 = 0.0000133681 cg/gal
1,000 nanograms per cubic foot = 0.0000133681 centigrams per gallon.

Frequently asked questions
How many centigrams per gallon are in 1 nanogram per cubic foot?
1 nanogram per cubic foot equals 1.336806e-8 centigrams per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per cubic foot to centigram per gallon?
Multiply the nanogram per cubic foot value by 1.336806e-8. The converter above does this instantly to whatever precision you set.
How do I convert centigram per gallon back to nanogram per cubic foot?
Use the reverse factor: 1 centigram per gallon equals 74,805,194.81 nanograms per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per cubic foot?
Nanogram per Cubic foot (ng/ft3) is a unit of density.
What is a centigram per gallon?
Centigram per Gallon (cg/gal) is a unit of density.
Is the nanogram per cubic foot to centigram per gallon conversion exact?
Yes. Both nanogram per cubic foot and centigram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 1.336806e-8 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.
