About Converting Drams per Oil barrel to Milligrams per Gallon
Dram per Oil barrel and Milligram 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
milligrams per gallon = drams per oil barrel × 42.1867903646
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 milligram per gallon equals 0.000264172052358 base units, so dividing one by the other gives the direct dram per oil barrel-to-milligram per gallon factor of 42.1867903646.
Simple example
1 dr/bbl × 42.18679036 = 42.18679036 mg/gal
1 dram per oil barrel = 42.18679036 milligrams per gallon.
Real-world example
1,000 dr/bbl × 42.18679036 = 42,186.79036 mg/gal
1,000 drams per oil barrel = 42,186.79036 milligrams per gallon.

What is a dram per oil barrel?
Dram per Oil barrel (dr/bbl) is a unit of density.
What is a milligram per gallon?
Milligram per Gallon (mg/gal) is a unit of density.
Is the dram per oil barrel to milligram per gallon conversion exact?
Yes. Both dram per oil barrel and milligram per gallon are defined by fixed standards rather than physical artifacts, so the factor of 42.18679036 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.
