About Converting Carats per Gallon to Grains per Quart
Carat per 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 = carats per gallon × 0.771617917647
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per gallon equals 0.0528344104716 base units, and 1 grain per quart equals 0.0684722441811 base units, so dividing one by the other gives the direct carat per gallon-to-grain per quart factor of 0.771617917647.
Simple example
1 ct/gal × 0.7716179176 = 0.7716179176 gr/qt
1 carat per gallon = 0.7716179176 grains per quart.
Real-world example
1,000 ct/gal × 0.7716179176 = 771.6179176 gr/qt
1,000 carats per gallon = 771.6179176 grains per quart.

Multiply the carat per gallon value by 0.7716179176. The converter above does this instantly to whatever precision you set.
How do I convert grain per quart back to carat per gallon?
Use the reverse factor: 1 grain per quart equals 1.2959782 carats per gallon. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
What is a grain per quart?
Grain per Quart (gr/qt) is a unit of density.
Is the carat per gallon to grain per quart conversion exact?
Yes. Both carat per gallon and grain per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.7716179176 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.
