About Converting Carats per Cubic Centimeter to Grains per Cubic Centimeter
Carat per Cubic Centimeter 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 cubic centimeter × 3.08647167059
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 cubic centimeter equals 64.79891 base units, so dividing one by the other gives the direct carat per cubic centimeter-to-grain per cubic centimeter factor of 3.08647167059.
Simple example
1 ct/cm3 × 3.086471671 = 3.086471671 gr/cm3
1 carat per cubic centimeter = 3.086471671 grains per cubic centimeter.
Real-world example
1,000 ct/cm3 × 3.086471671 = 3,086.471671 gr/cm3
1,000 carats per cubic centimeter = 3,086.471671 grains per cubic centimeter.

Frequently asked questions
How many grains per cubic centimeter are in 1 carat per cubic centimeter?
1 carat per cubic centimeter equals 3.086471671 grains per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic centimeter to grain per cubic centimeter?
Multiply the carat per cubic centimeter value by 3.086471671. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic centimeter back to carat per cubic centimeter?
Use the reverse factor: 1 grain per cubic centimeter equals 0.32399455 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 cubic centimeter?
Grain per Cubic Centimeter (gr/cm3) is a unit of density.
Is the carat per cubic centimeter to grain per cubic centimeter conversion exact?
Yes. Both carat per cubic centimeter and grain per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 3.086471671 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.
