About Converting Pounds per Gallon to Grains per Oil barrel
Pound per Gallon and Grain 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. Pound per Gallon is most often used for us paint and coatings density specifications.
Formula
grains per oil barrel = pounds per gallon × 294000
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per gallon equals 119.826427317 base units, and 1 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct pound per gallon-to-grain per oil barrel factor of 294000.
Simple example
1 lb/gal × 294000 = 294,000 gr/bbl
1 pound per gallon = 294,000 grains per oil barrel.
Real-world example
1,000 lb/gal × 294000 = 294,000,000 gr/bbl
1,000 pounds per gallon = 294,000,000 grains per oil barrel.

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.
