About Converting Carats per Quart to Grains per Gallon
Carat per Quart and Grain 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
grains per gallon = carats per quart × 12.3458866824
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per quart equals 0.211337641887 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct carat per quart-to-grain per gallon factor of 12.3458866824.
Simple example
1 ct/qt × 12.34588668 = 12.34588668 gr/gal
1 carat per quart = 12.34588668 grains per gallon.
Real-world example
1,000 ct/qt × 12.34588668 = 12,345.88668 gr/gal
1,000 carats per quart = 12,345.88668 grains per gallon.

What is a carat per quart?
Carat per Quart (ct/qt) is a unit of density.
What is a grain per gallon?
Grain per Gallon (gr/gal) is a unit of density.
Is the carat per quart to grain per gallon conversion exact?
Yes. Both carat per quart and grain per gallon are defined by fixed standards rather than physical artifacts, so the factor of 12.34588668 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.
