About Converting Nanograms per Gallon to Picograms per Imperial gallon
Nanogram per Gallon and Picogram per Imperial 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 imperial gallon = nanograms per gallon × 1200.9499255
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 imperial gallon equals 2.199692e-13 base units, so dividing one by the other gives the direct nanogram per gallon-to-picogram per imperial gallon factor of 1200.9499255.
Simple example
1 ng/gal × 1200.949926 = 1,200.949926 pg/imp gal
1 nanogram per gallon = 1,200.949926 picograms per imperial gallon.
Real-world example
1,000 ng/gal × 1200.949926 = 1,200,949.926 pg/imp gal
1,000 nanograms per gallon = 1,200,949.926 picograms per imperial gallon.

Frequently asked questions
How many picograms per imperial gallon are in 1 nanogram per gallon?
1 nanogram per gallon equals 1,200.949926 picograms per imperial gallon, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per gallon to picogram per imperial gallon?
Multiply the nanogram per gallon value by 1200.949926. The converter above does this instantly to whatever precision you set.
How do I convert picogram per imperial gallon back to nanogram per gallon?
Use the reverse factor: 1 picogram per imperial gallon equals 0.0008326742 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 imperial gallon?
Picogram per Imperial gallon (pg/imp gal) is a unit of density.
Is the nanogram per gallon to picogram per imperial gallon conversion exact?
Yes. Both nanogram per gallon and picogram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 1200.949926 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.
