About Converting Grains per Quart to Imperial hundredweights per Gallon
Grain per Quart and Imperial hundredweight per Gallon 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
imperial hundredweights per gallon = grains per quart × 0.00000510204081633
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per quart equals 0.0684722441811 base units, and 1 imperial hundredweight per gallon equals 13420.5598595 base units, so dividing one by the other gives the direct grain per quart-to-imperial hundredweight per gallon factor of 0.00000510204081633.
Simple example
1 gr/qt × 0.000005102040816 = 0.000005102 long cwt/gal
1 grain per quart = 0.000005102 imperial hundredweights per gallon.
Real-world example
1,000 gr/qt × 0.000005102040816 = 0.0051020408 long cwt/gal
1,000 grains per quart = 0.0051020408 imperial hundredweights per gallon.

What is a grain per quart?
Grain per Quart (gr/qt) is a unit of density.
What is a imperial hundredweight per gallon?
Imperial hundredweight per Gallon (long cwt/gal) is a unit of density.
Is the grain per quart to imperial hundredweight per gallon conversion exact?
Yes. Both grain per quart and imperial hundredweight per gallon are defined by fixed standards rather than physical artifacts, so the factor of 0.000005102040816 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.
