About Converting Nanograms per Gallon to Picograms per Cubic Centimeter
Nanogram per Gallon and Picogram 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
picograms per cubic centimeter = nanograms per gallon × 0.264172052358
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per gallon equals 2.641721e-10 base units, and 1 picogram per cubic centimeter equals 1e-9 base units, so dividing one by the other gives the direct nanogram per gallon-to-picogram per cubic centimeter factor of 0.264172052358.
Simple example
1 ng/gal × 0.2641720524 = 0.2641720524 pg/cm3
1 nanogram per gallon = 0.2641720524 picograms per cubic centimeter.
Real-world example
1,000 ng/gal × 0.2641720524 = 264.1720524 pg/cm3
1,000 nanograms per gallon = 264.1720524 picograms per cubic centimeter.

Frequently asked questions
How many picograms per cubic centimeter are in 1 nanogram per gallon?
1 nanogram per gallon equals 0.2641720524 picograms per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per gallon to picogram per cubic centimeter?
Multiply the nanogram per gallon value by 0.2641720524. The converter above does this instantly to whatever precision you set.
How do I convert picogram per cubic centimeter back to nanogram per gallon?
Use the reverse factor: 1 picogram per cubic centimeter equals 3.785411784 nanograms per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per gallon?
Nanogram per Gallon (ng/gal) is a unit of density.
What is a picogram per cubic centimeter?
Picogram per Cubic Centimeter (pg/cm3) is a unit of density.
Is the nanogram per gallon to picogram per cubic centimeter conversion exact?
Yes. Both nanogram per gallon and picogram per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.2641720524 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.
