About Converting Drams per Oil barrel to Stones per Gallon
Dram per Oil barrel and Stone 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
stones per gallon = drams per oil barrel × 0.00000664328231293
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per oil barrel equals 0.011144570993 base units, and 1 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct dram per oil barrel-to-stone per gallon factor of 0.00000664328231293.
Simple example
1 dr/bbl × 0.000006643282313 = 0.0000066433 st/gal
1 dram per oil barrel = 0.0000066433 stones per gallon.
Real-world example
1,000 dr/bbl × 0.000006643282313 = 0.0066432823 st/gal
1,000 drams per oil barrel = 0.0066432823 stones per gallon.

What is a dram per oil barrel?
Dram per Oil barrel (dr/bbl) is a unit of density.
What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
Is the dram per oil barrel to stone per gallon conversion exact?
Yes. Both dram per oil barrel and stone per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.000006643282313 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.
