About Converting Long tons per Oil barrel to Pounds per Gallon
Long ton per Oil barrel and Pound 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
pounds per gallon = long tons per oil barrel × 53.3333333333
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per oil barrel equals 6390.74279023 base units, and 1 pound per gallon equals 119.826427317 base units, so dividing one by the other gives the direct long ton per oil barrel-to-pound per gallon factor of 53.3333333333.
Simple example
1 long ton/bbl × 53.33333333 = 53.33333333 lb/gal
1 long ton per oil barrel = 53.33333333 pounds per gallon.
Real-world example
1,000 long ton/bbl × 53.33333333 = 53,333.33333 lb/gal
1,000 long tons per oil barrel = 53,333.33333 pounds per gallon.

Understanding the Long ton per Oil barrel (long ton/bbl)
Mass per volume density.
Understanding the Pound per Gallon
Pound per Gallon (lb/gal) measures density. The US customary unit for liquid density, based on the US gallon (231 cubic inches). It is classified as a US customary density unit.
Where it's used: United States (paint, fuel, and industrial liquid density specifications)
lb/gal vs. lb/ft³. Both are US customary density units; they're related through the real, fixed relationship between the US gallon and the cubic foot (1 cubic foot ≈ 7.48 US gallons), not a round conversion factor.
Uses of the Pound per Gallon today
- US paint and coatings density specifications
- US fuel and petroleum liquid density specs
- Industrial liquid handling and shipping weight calculations
