About Converting Imperial hundredweights per Gallon to Grains per Oil barrel
Imperial hundredweight per Gallon 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 = imperial hundredweights per gallon × 32928000
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial hundredweight per gallon equals 13420.5598595 base units, and 1 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct imperial hundredweight per gallon-to-grain per oil barrel factor of 32928000.
Simple example
1 long cwt/gal × 32928000 = 32,928,000 gr/bbl
1 imperial hundredweight per gallon = 32,928,000 grains per oil barrel.
Real-world example
1,000 long cwt/gal × 32928000 = 32,928,000,000 gr/bbl
1,000 imperial hundredweights per gallon = 32,928,000,000 grains per oil barrel.

What is a imperial hundredweight per gallon?
Imperial hundredweight per Gallon (long cwt/gal) 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 imperial hundredweight per gallon to grain per oil barrel conversion exact?
Yes. Both imperial hundredweight per gallon and grain per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 32928000 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.
