About Converting Grains per Cubic Centimeter to Carat per Cubic inches
Grain per Cubic Centimeter and Carat per Cubic inch 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
carat per cubic inches = grains per cubic centimeter × 5.3093194265
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cubic centimeter equals 64.79891 base units, and 1 carat per cubic inch equals 12.2047488189 base units, so dividing one by the other gives the direct grain per cubic centimeter-to-carat per cubic inch factor of 5.3093194265.
Simple example
1 gr/cm3 × 5.309319427 = 5.309319427 ct/in3
1 grain per cubic centimeter = 5.309319427 carat per cubic inches.
Real-world example
1,000 gr/cm3 × 5.309319427 = 5,309.319427 ct/in3
1,000 grains per cubic centimeter = 5,309.319427 carat per cubic inches.

Frequently asked questions
How many carat per cubic inches are in 1 grain per cubic centimeter?
1 grain per cubic centimeter equals 5.309319427 carat per cubic inches, using the exact defined conversion factor rather than an estimate.
How do I convert grain per cubic centimeter to carat per cubic inch?
Multiply the grain per cubic centimeter value by 5.309319427. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic inch back to grain per cubic centimeter?
Use the reverse factor: 1 carat per cubic inch equals 0.1883480574 grains per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a grain per cubic centimeter?
Grain per Cubic Centimeter (gr/cm3) is a unit of density.
What is a carat per cubic inch?
Carat per Cubic inch (ct/in3) is a unit of density.
Is the grain per cubic centimeter to carat per cubic inch conversion exact?
Yes. Both grain per cubic centimeter and carat per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 5.309319427 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.
