About Converting Stones per Oil barrel to Drams per Gallon
Stone per Oil barrel and Dram per Gallon 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
drams per gallon = stones per oil barrel × 85.3333333333
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per oil barrel equals 39.942142439 base units, and 1 dram per gallon equals 0.468071981707 base units, so dividing one by the other gives the direct stone per oil barrel-to-dram per gallon factor of 85.3333333333.
Simple example
1 st/bbl × 85.33333333 = 85.33333333 dr/gal
1 stone per oil barrel = 85.33333333 drams per gallon.
Real-world example
1,000 st/bbl × 85.33333333 = 85,333.33333 dr/gal
1,000 stones per oil barrel = 85,333.33333 drams per gallon.

What is a stone per oil barrel?
Stone per Oil barrel (st/bbl) is a unit of density.
What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
Is the stone per oil barrel to dram per gallon conversion exact?
Yes. Both stone per oil barrel and dram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 85.33333333 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.
