About Converting Grains per Oil barrel to Milligrams per Oil barrel
Grain per Oil barrel and Milligram 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
milligrams per oil barrel = grains per oil barrel × 64.79891
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per oil barrel equals 0.00040757288203 base units, and 1 milligram per oil barrel equals 0.00000628981077043 base units, so dividing one by the other gives the direct grain per oil barrel-to-milligram per oil barrel factor of 64.79891.
Simple example
1 gr/bbl × 64.79891 = 64.79891 mg/bbl
1 grain per oil barrel = 64.79891 milligrams per oil barrel.
Real-world example
1,000 gr/bbl × 64.79891 = 64,798.91 mg/bbl
1,000 grains per oil barrel = 64,798.91 milligrams per oil barrel.

What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) is a unit of density.
What is a milligram per oil barrel?
Milligram per Oil barrel (mg/bbl) is a unit of density.
Is the grain per oil barrel to milligram per oil barrel conversion exact?
Yes. Both grain per oil barrel and milligram per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 64.79891 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.
