About Converting Pounds per Cubic foot to Nanograms per Gallon
Pound per Cubic foot and Nanogram 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. Pound per Cubic foot is most often used for us construction material density specs (concrete, soil, lumber, insulation).
Formula
nanograms per gallon = pounds per cubic foot × 60636480017.4
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic foot equals 16.018463374 base units, and 1 nanogram per gallon equals 2.641721e-10 base units, so dividing one by the other gives the direct pound per cubic foot-to-nanogram per gallon factor of 60636480017.4.
Simple example
1 lb/ft3 × 60636480020 = 60,636,480,020 ng/gal
1 pound per cubic foot = 60,636,480,020 nanograms per gallon.
Real-world example
1,000 lb/ft3 × 60636480020 = 6.063648e+13 ng/gal
1,000 pounds per cubic foot = 6.063648e+13 nanograms per gallon.

What is a pound per cubic foot?
Pound per Cubic foot (lb/ft3) measures density. The US customary unit for expressing density, commonly used in construction and engineering material specifications. It is classified as a US customary density unit.
What is a nanogram per gallon?
Nanogram per Gallon (ng/gal) is a unit of density.
Is the pound per cubic foot to nanogram per gallon conversion exact?
Yes. Both pound per cubic foot and nanogram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 60636480020 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.
