About Converting Grains per Oil barrel to Long tons per Cubic yard
Grain per Oil barrel and Long ton per Cubic yard 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 cubic yard = grains per oil barrel × 3.066904e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per oil barrel equals 0.00040757288203 base units, and 1 long ton per cubic yard equals 1328.93918362 base units, so dividing one by the other gives the direct grain per oil barrel-to-long ton per cubic yard factor of 3.066904e-7.
Simple example
1 gr/bbl × 3.066904e-7 = 3.066904e-7 long ton/yd3
1 grain per oil barrel = 3.066904e-7 long tons per cubic yard.
Real-world example
1,000 gr/bbl × 3.066904e-7 = 0.0003066904 long ton/yd3
1,000 grains per oil barrel = 0.0003066904 long tons per cubic yard.

What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) is a unit of density.
What is a long ton per cubic yard?
Long ton per Cubic yard (long ton/yd3) is a unit of density.
Is the grain per oil barrel to long ton per cubic yard conversion exact?
Yes. Both grain per oil barrel and long ton per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 3.066904e-7 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.
