About Converting Picograms per Cubic foot to Nanograms per Gallon
Picogram 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. Both are mass per volume density units.
Formula
nanograms per gallon = picograms per cubic foot × 0.000133680555556
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per cubic foot equals 3.531467e-14 base units, and 1 nanogram per gallon equals 2.641721e-10 base units, so dividing one by the other gives the direct picogram per cubic foot-to-nanogram per gallon factor of 0.000133680555556.
Simple example
1 pg/ft3 × 0.0001336805556 = 0.0001336806 ng/gal
1 picogram per cubic foot = 0.0001336806 nanograms per gallon.
Real-world example
1,000 pg/ft3 × 0.0001336805556 = 0.1336805556 ng/gal
1,000 picograms per cubic foot = 0.1336805556 nanograms per gallon.

Frequently asked questions
How many nanograms per gallon are in 1 picogram per cubic foot?
1 picogram per cubic foot equals 0.0001336806 nanograms per gallon, using the exact defined conversion factor rather than an estimate.
How do I convert picogram per cubic foot to nanogram per gallon?
Multiply the picogram per cubic foot value by 0.0001336805556. The converter above does this instantly to whatever precision you set.
How do I convert nanogram per gallon back to picogram per cubic foot?
Use the reverse factor: 1 nanogram per gallon equals 7,480.519481 picograms per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a picogram per cubic foot?
Picogram per Cubic foot (pg/ft3) is a unit of density.
What is a nanogram per gallon?
Nanogram per Gallon (ng/gal) is a unit of density.
Is the picogram per cubic foot to nanogram per gallon conversion exact?
Yes. Both picogram per cubic foot and nanogram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.0001336805556 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.
