About Converting Drams per Quart to Stones per Oil barrel
Dram 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 = drams per quart × 0.046875
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per quart equals 1.87228792683 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct dram per quart-to-stone per oil barrel factor of 0.046875.
Simple example
1 dr/qt × 0.046875 = 0.046875 st/bbl
1 dram per quart = 0.046875 stones per oil barrel.
Real-world example
1,000 dr/qt × 0.046875 = 46.875 st/bbl
1,000 drams per quart = 46.875 stones per oil barrel.

What is a dram per quart?
Dram per Quart (dr/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 dram per quart to stone per oil barrel conversion exact?
Yes. Both dram per quart and stone per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.046875 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.
