About Converting Drams per Gallon to Megagrams per Oil barrel
Dram per Gallon and Megagram 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
megagrams per oil barrel = drams per gallon × 0.0000744174982031
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per gallon equals 0.468071981707 base units, and 1 megagram per oil barrel equals 6289.81077043 base units, so dividing one by the other gives the direct dram per gallon-to-megagram per oil barrel factor of 0.0000744174982031.
Simple example
1 dr/gal × 0.0000744174982 = 0.0000744175 Mg/bbl
1 dram per gallon = 0.0000744175 megagrams per oil barrel.
Real-world example
1,000 dr/gal × 0.0000744174982 = 0.0744174982 Mg/bbl
1,000 drams per gallon = 0.0744174982 megagrams per oil barrel.

What is a dram per gallon?
Dram per Gallon (dr/gal) is a unit of density.
What is a megagram per oil barrel?
Megagram per Oil barrel (Mg/bbl) is a unit of density.
Is the dram per gallon to megagram per oil barrel conversion exact?
Yes. Both dram per gallon and megagram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.0000744174982 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.
