About Converting Grains per Gallon to US hundredweights per Quart
Grain per Gallon and US hundredweight per Quart 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 quart = grains per gallon × 3.571429e-7
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 quart equals 47930.5709268 base units, so dividing one by the other gives the direct grain per gallon-to-us hundredweight per quart factor of 3.571429e-7.
Simple example
1 gr/gal × 3.571429e-7 = 3.571429e-7 cwt/qt
1 grain per gallon = 3.571429e-7 us hundredweights per quart.
Real-world example
1,000 gr/gal × 3.571429e-7 = 0.0003571429 cwt/qt
1,000 grains per gallon = 0.0003571429 us hundredweights per quart.

What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
What is a us hundredweight per quart?
US hundredweight per Quart (cwt/qt) is a unit of density.
Is the grain per gallon to us hundredweight per quart conversion exact?
Yes. Both grain per gallon and us hundredweight per quart are defined by fixed standards rather than physical artifacts, so the factor of 3.571429e-7 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.
