About Converting Pound per Cubic inches to Grains per Oil barrel
Pound 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. Pound per Cubic inch is most often used for used in machining and materials engineering, particularly for describing the density of metals, where a smaller volume unit than the cubic foot gives a more convenient figure.
Formula
grains per oil barrel = pound per cubic inches × 67914000
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic inch equals 27679.9047102 base units, and 1 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct pound per cubic inch-to-grain per oil barrel factor of 67914000.
Simple example
1 lb/in3 × 67914000 = 67,914,000 gr/bbl
1 pound per cubic inch = 67,914,000 grains per oil barrel.
Real-world example
1,000 lb/in3 × 67914000 = 67,914,000,000 gr/bbl
1,000 pound per cubic inches = 67,914,000,000 grains per oil barrel.

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.
