About Converting Carats per Quart to Grains per Liter
Carat per Quart and Grain per Liter 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 liter = carats per quart × 3.26143822306
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 liter equals 0.06479891 base units, so dividing one by the other gives the direct carat per quart-to-grain per liter factor of 3.26143822306.
Simple example
1 ct/qt × 3.261438223 = 3.261438223 gr/L
1 carat per quart = 3.261438223 grains per liter.
Real-world example
1,000 ct/qt × 3.261438223 = 3,261.438223 gr/L
1,000 carats per quart = 3,261.438223 grains per liter.

How do I convert grain per liter back to carat per quart?
Use the reverse factor: 1 grain per liter equals 0.3066131969 carats per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per quart?
Carat per Quart (ct/qt) is a unit of density.
What is a grain per liter?
Grain per Liter (gr/L) is a unit of density.
Is the carat per quart to grain per liter conversion exact?
Yes. Both carat per quart and grain per liter are defined by fixed standards rather than physical artifacts, so the factor of 3.261438223 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.
