About Converting Drams per Quart to Pounds per Oil barrel
Dram per Quart and Pound 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
pounds per oil barrel = drams per quart × 0.65625
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 pound per oil barrel equals 2.85301017421 base units, so dividing one by the other gives the direct dram per quart-to-pound per oil barrel factor of 0.65625.
Simple example
1 dr/qt × 0.65625 = 0.65625 lb/bbl
1 dram per quart = 0.65625 pounds per oil barrel.
Real-world example
1,000 dr/qt × 0.65625 = 656.25 lb/bbl
1,000 drams per quart = 656.25 pounds per oil barrel.

What is a dram per quart?
Dram per Quart (dr/qt) is a unit of density.
What is a pound per oil barrel?
Pound per Oil barrel (lb/bbl) is a unit of density.
Is the dram per quart to pound per oil barrel conversion exact?
Yes. Both dram per quart and pound per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.65625 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.
