About Converting Grains per Cubic yard to Stones per Oil barrel
Grain per Cubic yard and Stone 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. Both are mass per volume density units.
Formula
stones per oil barrel = grains per cubic yard × 0.00000212191358025
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic yard equals 0.0000847537744654 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct grain per cubic yard-to-stone per oil barrel factor of 0.00000212191358025.
Simple example
1 gr/yd3 × 0.00000212191358 = 0.0000021219 st/bbl
1 grain per cubic yard = 0.0000021219 stones per oil barrel.
Real-world example
1,000 gr/yd3 × 0.00000212191358 = 0.0021219136 st/bbl
1,000 grains per cubic yard = 0.0021219136 stones per oil barrel.

What is a grain per cubic yard?
Grain per Cubic yard (gr/yd3) is a unit of density.
What is a stone per oil barrel?
Stone per Oil barrel (st/bbl) is a unit of density.
Is the grain per cubic yard to stone per oil barrel conversion exact?
Yes. Both grain per cubic yard and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.00000212191358 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.
