About Converting Grains per Quart to Carats per Cubic Centimeter
Grain per Quart and Carat 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
carats per cubic centimeter = grains per quart × 0.000342361220905
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per quart equals 0.0684722441811 base units, and 1 carat per cubic centimeter equals 200 base units, so dividing one by the other gives the direct grain per quart-to-carat per cubic centimeter factor of 0.000342361220905.
Simple example
1 gr/qt × 0.0003423612209 = 0.0003423612 ct/cm3
1 grain per quart = 0.0003423612 carats per cubic centimeter.
Real-world example
1,000 gr/qt × 0.0003423612209 = 0.3423612209 ct/cm3
1,000 grains per quart = 0.3423612209 carats per cubic centimeter.

Frequently asked questions
How many carats per cubic centimeter are in 1 grain per quart?
1 grain per quart equals 0.0003423612 carats per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert grain per quart to carat per cubic centimeter?
Multiply the grain per quart value by 0.0003423612209. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic centimeter back to grain per quart?
Use the reverse factor: 1 carat per cubic centimeter equals 2,920.891558 grains per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per quart?
Grain per Quart (gr/qt) is a unit of density.
What is a carat per cubic centimeter?
Carat per Cubic Centimeter (ct/cm3) is a unit of density.
Is the grain per quart to carat per cubic centimeter conversion exact?
Yes. Both grain per quart and carat per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.0003423612209 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.
