About Converting Pounds per Oil barrel to Grains per Quart
Pound per Oil barrel and Grain per Quart 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
grains per quart = pounds per oil barrel × 41.6666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per oil barrel equals 2.85301017421 base units, and 1 grain per quart equals 0.0684722441811 base units, so dividing one by the other gives the direct pound per oil barrel-to-grain per quart factor of 41.6666666667.
Simple example
1 lb/bbl × 41.66666667 = 41.66666667 gr/qt
1 pound per oil barrel = 41.66666667 grains per quart.
Real-world example
1,000 lb/bbl × 41.66666667 = 41,666.66667 gr/qt
1,000 pounds per oil barrel = 41,666.66667 grains per quart.

What is a pound per oil barrel?
Pound per Oil barrel (lb/bbl) is a unit of density.
What is a grain per quart?
Grain per Quart (gr/qt) is a unit of density.
Is the pound per oil barrel to grain per quart conversion exact?
Yes. Both pound per oil barrel and grain per quart are defined by fixed standards rather than physical artifacts, so the factor of 41.66666667 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.
