About Converting Picograms per Gallon to Picograms per Imperial gallon
Picogram 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 = picograms per gallon × 1.2009499255
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per gallon equals 2.641721e-13 base units, and 1 picogram per imperial gallon equals 2.199692e-13 base units, so dividing one by the other gives the direct picogram per gallon-to-picogram per imperial gallon factor of 1.2009499255.
Simple example
1 pg/gal × 1.200949926 = 1.200949926 pg/imp gal
1 picogram per gallon = 1.200949926 picograms per imperial gallon.
Real-world example
1,000 pg/gal × 1.200949926 = 1,200.949926 pg/imp gal
1,000 picograms per gallon = 1,200.949926 picograms per imperial gallon.

What is a picogram per gallon?
Picogram per Gallon (pg/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 picogram per gallon to picogram per imperial gallon conversion exact?
Yes. Both picogram per gallon and picogram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 1.200949926 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.
