About Converting Carats per Quart to Grains per Cubic Centimeter
Carat per Quart and Grain per Cubic Centimeter 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 cubic centimeter = carats per quart × 0.00326143822306
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 cubic centimeter equals 64.79891 base units, so dividing one by the other gives the direct carat per quart-to-grain per cubic centimeter factor of 0.00326143822306.
Simple example
1 ct/qt × 0.003261438223 = 0.0032614382 gr/cm3
1 carat per quart = 0.0032614382 grains per cubic centimeter.
Real-world example
1,000 ct/qt × 0.003261438223 = 3.261438223 gr/cm3
1,000 carats per quart = 3.261438223 grains per cubic centimeter.

Frequently asked questions
How many grains per cubic centimeter are in 1 carat per quart?
1 carat per quart equals 0.0032614382 grains per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per quart to grain per cubic centimeter?
Multiply the carat per quart value by 0.003261438223. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic centimeter back to carat per quart?
Use the reverse factor: 1 grain per cubic centimeter equals 306.6131969 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 cubic centimeter?
Grain per Cubic Centimeter (gr/cm3) is a unit of density.
Is the carat per quart to grain per cubic centimeter conversion exact?
Yes. Both carat per quart and grain per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.003261438223 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.
