About Converting Megagrams per Oil barrel to Drams per Cup
Megagram per Oil barrel and Dram per Cup 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
drams per cup = megagrams per oil barrel × 839.856236895
This factor comes from each unit's defined relationship to the category's base unit: 1 megagram per oil barrel equals 6289.81077043 base units, and 1 dram per cup equals 7.48915170731 base units, so dividing one by the other gives the direct megagram per oil barrel-to-dram per cup factor of 839.856236895.
Simple example
1 Mg/bbl × 839.8562369 = 839.8562369 dr/cup
1 megagram per oil barrel = 839.8562369 drams per cup.
Real-world example
1,000 Mg/bbl × 839.8562369 = 839,856.2369 dr/cup

What is a megagram per oil barrel?
Megagram per Oil barrel (Mg/bbl) is a unit of density.
What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
Is the megagram per oil barrel to dram per cup conversion exact?
Yes. Both megagram per oil barrel and dram per cup are defined by fixed standards rather than physical artifacts, so the factor of 839.8562369 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.
