About Converting Grains per Gallon to US hundredweights per Oil barrel
Grain per Gallon and US hundredweight 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
us hundredweights per oil barrel = grains per gallon × 0.00006
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per gallon equals 0.0171180610453 base units, and 1 us hundredweight per oil barrel equals 285.301017421 base units, so dividing one by the other gives the direct grain per gallon-to-us hundredweight per oil barrel factor of 0.00006.
Simple example
1 gr/gal × 0.00006 = 0.00006 cwt/bbl
1 grain per gallon = 0.00006 us hundredweights per oil barrel.
Real-world example
1,000 gr/gal × 0.00006 = 0.06 cwt/bbl
1,000 grains per gallon = 0.06 us hundredweights per oil barrel.

What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
What is a us hundredweight per oil barrel?
US hundredweight per Oil barrel (cwt/bbl) is a unit of density.
Is the grain per gallon to us hundredweight per oil barrel conversion exact?
Yes. Both grain per gallon and us hundredweight per oil barrel are defined by fixed standards rather than physical artifacts, so the factor of 0.00006 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.
