About Converting Milligram per Cubic inches to Grains per Oil barrel
Milligram per Cubic inch and Grain 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
grains per oil barrel = milligram per cubic inches × 149.72474074
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per cubic inch equals 0.0610237440947 base units, and 1 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct milligram per cubic inch-to-grain per oil barrel factor of 149.72474074.
Simple example
1 mg/in3 × 149.7247407 = 149.7247407 gr/bbl
1 milligram per cubic inch = 149.7247407 grains per oil barrel.
Real-world example
1,000 mg/in3 × 149.7247407 = 149,724.7407 gr/bbl
1,000 milligram per cubic inches = 149,724.7407 grains per oil barrel.

What is a milligram per cubic inch?
Milligram per Cubic inch (mg/in3) is a unit of density.
What is a grain per oil barrel?
Grain per Oil barrel (gr/bbl) is a unit of density.
Is the milligram per cubic inch to grain per oil barrel conversion exact?
Yes. Both milligram per cubic inch and grain per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 149.7247407 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.
