About Converting Grains per Quart to Stones per Oil barrel
Grain per Quart 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 quart × 0.00171428571429
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per quart equals 0.0684722441811 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct grain per quart-to-stone per oil barrel factor of 0.00171428571429.
Simple example
1 gr/qt × 0.001714285714 = 0.0017142857 st/bbl
1 grain per quart = 0.0017142857 stones per oil barrel.
Real-world example
1,000 gr/qt × 0.001714285714 = 1.714285714 st/bbl
1,000 grains per quart = 1.714285714 stones per oil barrel.

What is a grain per quart?
Grain per Quart (gr/qt) 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 quart to stone per oil barrel conversion exact?
Yes. Both grain per quart and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.001714285714 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.
