About Converting Picograms per Imperial gallon to Long tons per Oil barrel
Picogram per Imperial gallon and Long ton per Oil barrel 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
long tons per oil barrel = picograms per imperial gallon × 3.441998e-17
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per imperial gallon equals 2.199692e-13 base units, and 1 long ton per oil barrel equals 6390.74279023 base units, so dividing one by the other gives the direct picogram per imperial gallon-to-long ton per oil barrel factor of 3.441998e-17.
Simple example
1 pg/imp gal × 3.441998e-17 = 3.441998e-17 long ton/bbl
1 picogram per imperial gallon = 3.441998e-17 long tons per oil barrel.
Real-world example
1,000 pg/imp gal × 3.441998e-17 = 3.441998e-14 long ton/bbl
1,000 picograms per imperial gallon = 3.441998e-14 long tons per oil barrel.

What is a picogram per imperial gallon?
Picogram per Imperial gallon (pg/imp gal) is a unit of density.
What is a long ton per oil barrel?
Long ton per Oil barrel (long ton/bbl) is a unit of density.
Is the picogram per imperial gallon to long ton per oil barrel conversion exact?
Yes. Both picogram per imperial gallon and long ton per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 3.441998e-17 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.
