About Converting Nanograms per Imperial gallon to Picograms per Gallon
Nanogram per Imperial gallon and Picogram 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
picograms per gallon = nanograms per imperial gallon × 832.674184629
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per imperial gallon equals 2.199692e-10 base units, and 1 picogram per gallon equals 2.641721e-13 base units, so dividing one by the other gives the direct nanogram per imperial gallon-to-picogram per gallon factor of 832.674184629.
Simple example
1 ng/imp gal × 832.6741846 = 832.6741846 pg/gal
1 nanogram per imperial gallon = 832.6741846 picograms per gallon.
Real-world example
1,000 ng/imp gal × 832.6741846 = 832,674.1846 pg/gal
1,000 nanograms per imperial gallon = 832,674.1846 picograms per gallon.

Multiply the nanogram per imperial gallon value by 832.6741846. The converter above does this instantly to whatever precision you set.
How do I convert picogram per gallon back to nanogram per imperial gallon?
Use the reverse factor: 1 picogram per gallon equals 0.0012009499 nanograms per imperial gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per imperial gallon?
Nanogram per Imperial gallon (ng/imp gal) is a unit of density.
What is a picogram per gallon?
Picogram per Gallon (pg/gal) is a unit of density.
Is the nanogram per imperial gallon to picogram per gallon conversion exact?
Yes. Both nanogram per imperial gallon and picogram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 832.6741846 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.
