About Converting Grams per Imperial gallon to Grains per Quart
Gram per Imperial gallon and Grain 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
grains per quart = grams per imperial gallon × 3.21253160211
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per imperial gallon equals 0.219969248299 base units, and 1 grain per quart equals 0.0684722441811 base units, so dividing one by the other gives the direct gram per imperial gallon-to-grain per quart factor of 3.21253160211.
Simple example
1 g/imp gal × 3.212531602 = 3.212531602 gr/qt
1 gram per imperial gallon = 3.212531602 grains per quart.
Real-world example
1,000 g/imp gal × 3.212531602 = 3,212.531602 gr/qt
1,000 grams per imperial gallon = 3,212.531602 grains per quart.

What is a gram per imperial gallon?
Gram per Imperial gallon (g/imp gal) is a unit of density.
What is a grain per quart?
Grain per Quart (gr/qt) is a unit of density.
Is the gram per imperial gallon to grain per quart conversion exact?
Yes. Both gram per imperial gallon and grain per quart are defined by fixed standards rather than physical artifacts, so the factor of 3.212531602 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.
