About Converting Carat per Cubic inches to Gram per Cubic inches
Carat per Cubic inch and Gram 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
gram per cubic inches = carat per cubic inches × 0.2
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic inch equals 12.2047488189 base units, and 1 gram per cubic inch equals 61.0237440947 base units, so dividing one by the other gives the direct carat per cubic inch-to-gram per cubic inch factor of 0.2.
Simple example
1 ct/in3 × 0.2 = 0.2 g/in3
1 carat per cubic inch = 0.2 gram per cubic inches.
Real-world example
1,000 ct/in3 × 0.2 = 200 g/in3
1,000 carat per cubic inches = 200 gram per cubic inches.

Frequently asked questions
How many gram per cubic inches are in 1 carat per cubic inch?
1 carat per cubic inch equals 0.2 gram per cubic inches, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic inch to gram per cubic inch?
Multiply the carat per cubic inch value by 0.2. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic inch back to carat per cubic inch?
Use the reverse factor: 1 gram per cubic inch equals 5 carat per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic inch?
Carat per Cubic inch (ct/in3) is a unit of density.
What is a gram per cubic inch?
Gram per Cubic inch (g/in3) is a unit of density.
Is the carat per cubic inch to gram per cubic inch conversion exact?
Yes. Both carat per cubic inch and gram per cubic inch are defined by fixed standards rather than physical artifacts, so the factor of 0.2 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.
