About Converting Centigram per Cubic inches to Carats per Cup
Centigram per Cubic inch and Carat per Cup 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 cup = centigram per cubic inches × 0.721875
This factor comes from each unit's defined relationship to the category's base unit: 1 centigram per cubic inch equals 0.610237440947 base units, and 1 carat per cup equals 0.845350567546 base units, so dividing one by the other gives the direct centigram per cubic inch-to-carat per cup factor of 0.721875.
Simple example
1 cg/in3 × 0.721875 = 0.721875 ct/cup
1 centigram per cubic inch = 0.721875 carats per cup.
Real-world example
1,000 cg/in3 × 0.721875 = 721.875 ct/cup
1,000 centigram per cubic inches = 721.875 carats per cup.

Frequently asked questions
How many carats per cup are in 1 centigram per cubic inch?
1 centigram per cubic inch equals 0.721875 carats per cup, using the exact defined conversion factor rather than an estimate.
How do I convert centigram per cubic inch to carat per cup?
Multiply the centigram per cubic inch value by 0.721875. The converter above does this instantly to whatever precision you set.
How do I convert carat per cup back to centigram per cubic inch?
Use the reverse factor: 1 carat per cup equals 1.385281385 centigram per cubic inches. You can also use the swap control in the converter above to flip the direction instantly.
What is a centigram per cubic inch?
Centigram per Cubic inch (cg/in3) is a unit of density.
What is a carat per cup?
Carat per Cup (ct/cup) is a unit of density.
Is the centigram per cubic inch to carat per cup conversion exact?
Yes. Both centigram per cubic inch and carat per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.721875 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.
