About Converting Carat per Cubic inches to Kilograms per Cup
Carat per Cubic inch and Kilogram 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
kilograms per cup = carat per cubic inches × 0.0028875
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 kilogram per cup equals 4226.75283773 base units, so dividing one by the other gives the direct carat per cubic inch-to-kilogram per cup factor of 0.0028875.
Simple example
1 ct/in3 × 0.0028875 = 0.0028875 kg/cup
1 carat per cubic inch = 0.0028875 kilograms per cup.
Real-world example
1,000 ct/in3 × 0.0028875 = 2.8875 kg/cup
1,000 carat per cubic inches = 2.8875 kilograms per cup.

Frequently asked questions
How many kilograms per cup are in 1 carat per cubic inch?
1 carat per cubic inch equals 0.0028875 kilograms per cup, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic inch to kilogram per cup?
Multiply the carat per cubic inch value by 0.0028875. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per cup back to carat per cubic inch?
Use the reverse factor: 1 kilogram per cup equals 346.3203463 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 kilogram per cup?
Kilogram per Cup (kg/cup) is a unit of density.
Is the carat per cubic inch to kilogram per cup conversion exact?
Yes. Both carat per cubic inch and kilogram per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.0028875 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.
