About Converting Picograms per Oil barrel to Long tons per Gallon
Picogram per Oil barrel and Long ton 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
long tons per gallon = picograms per oil barrel × 2.343349e-20
This factor comes from each unit's defined relationship to the category's base unit: 1 picogram per oil barrel equals 6.289811e-15 base units, and 1 long ton per gallon equals 268411.19719 base units, so dividing one by the other gives the direct picogram per oil barrel-to-long ton per gallon factor of 2.343349e-20.
Simple example
1 pg/bbl × 2.343349e-20 = 2.343349e-20 long ton/gal
1 picogram per oil barrel = 2.343349e-20 long tons per gallon.
Real-world example
1,000 pg/bbl × 2.343349e-20 = 2.343349e-17 long ton/gal
1,000 picograms per oil barrel = 2.343349e-17 long tons per gallon.

What is a picogram per oil barrel?
Picogram per Oil barrel (pg/bbl) is a unit of density.
What is a long ton per gallon?
Long ton per Gallon (long ton/gal) is a unit of density.
Is the picogram per oil barrel to long ton per gallon conversion exact?
Yes. Both picogram per oil barrel and long ton per gallon are defined by fixed standards rather than physical artifacts, so the factor of 2.343349e-20 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.
