About Converting Grains per Oil barrel to Picograms per Imperial gallon
Grain per Oil barrel 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 = grains per oil barrel × 1852863003.27
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per oil barrel equals 0.00040757288203 base units, and 1 picogram per imperial gallon equals 2.199692e-13 base units, so dividing one by the other gives the direct grain per oil barrel-to-picogram per imperial gallon factor of 1852863003.27.
Simple example
1 gr/bbl × 1852863003 = 1,852,863,003 pg/imp gal
1 grain per oil barrel = 1,852,863,003 picograms per imperial gallon.
Real-world example
1,000 gr/bbl × 1852863003 = 1.852863e+12 pg/imp gal
1,000 grains per oil barrel = 1.852863e+12 picograms per imperial gallon.

What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) 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 grain per oil barrel to picogram per imperial gallon conversion exact?
Yes. Both grain per oil barrel and picogram per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 1852863003 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.
