About Converting Drams per Oil barrel to Grains per Quart
Dram per Oil barrel and Grain per Quart 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
grains per quart = drams per oil barrel × 0.162760416667
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 grain per quart equals 0.0684722441811 base units, so dividing one by the other gives the direct dram per oil barrel-to-grain per quart factor of 0.162760416667.
Simple example
1 dr/bbl × 0.1627604167 = 0.1627604167 gr/qt
1 dram per oil barrel = 0.1627604167 grains per quart.
Real-world example
1,000 dr/bbl × 0.1627604167 = 162.7604167 gr/qt
1,000 drams per oil barrel = 162.7604167 grains per quart.

Multiply the dram per oil barrel value by 0.1627604167. The converter above does this instantly to whatever precision you set.
How do I convert grain per quart back to dram per oil barrel?
Use the reverse factor: 1 grain per quart equals 6.144 drams per oil barrel. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per oil barrel?
Dram per Oil barrel (dr/bbl) is a unit of density.
What is a grain per quart?
Grain per Quart (gr/qt) is a unit of density.
Is the dram per oil barrel to grain per quart conversion exact?
Yes. Both dram per oil barrel and grain per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.1627604167 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.
