About Converting Carats per Cubic Centimeter to Grains per Quart
Carat per Cubic Centimeter 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 cubic centimeter × 2920.89155821
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic centimeter equals 200 base units, and 1 grain per quart equals 0.0684722441811 base units, so dividing one by the other gives the direct carat per cubic centimeter-to-grain per quart factor of 2920.89155821.
Simple example
1 ct/cm3 × 2920.891558 = 2,920.891558 gr/qt
1 carat per cubic centimeter = 2,920.891558 grains per quart.
Real-world example
1,000 ct/cm3 × 2920.891558 = 2,920,891.558 gr/qt
1,000 carats per cubic centimeter = 2,920,891.558 grains per quart.

Frequently asked questions
How many grains per quart are in 1 carat per cubic centimeter?
1 carat per cubic centimeter equals 2,920.891558 grains per quart, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic centimeter to grain per quart?
Multiply the carat per cubic centimeter value by 2920.891558. The converter above does this instantly to whatever precision you set.
How do I convert grain per quart back to carat per cubic centimeter?
Use the reverse factor: 1 grain per quart equals 0.0003423612 carats per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic centimeter?
Carat per Cubic Centimeter (ct/cm3) 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 cubic centimeter to grain per quart conversion exact?
Yes. Both carat per cubic centimeter and grain per quart are defined by fixed standards rather than physical artifacts, so the factor of 2920.891558 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.
