About Converting Carats per Cubic Centimeter to Stones per Cup
Carat per Cubic Centimeter and Stone 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
stones per cup = carats per cubic centimeter × 0.00745125397502
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 stone per cup equals 26841.119719 base units, so dividing one by the other gives the direct carat per cubic centimeter-to-stone per cup factor of 0.00745125397502.
Simple example
1 ct/cm3 × 0.007451253975 = 0.007451254 st/cup
1 carat per cubic centimeter = 0.007451254 stones per cup.
Real-world example
1,000 ct/cm3 × 0.007451253975 = 7.451253975 st/cup
1,000 carats per cubic centimeter = 7.451253975 stones per cup.

Frequently asked questions
How many stones per cup are in 1 carat per cubic centimeter?
1 carat per cubic centimeter equals 0.007451254 stones per cup, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic centimeter to stone per cup?
Multiply the carat per cubic centimeter value by 0.007451253975. The converter above does this instantly to whatever precision you set.
How do I convert stone per cup back to carat per cubic centimeter?
Use the reverse factor: 1 stone per cup equals 134.2055986 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 stone per cup?
Stone per Cup (st/cup) is a unit of density.
Is the carat per cubic centimeter to stone per cup conversion exact?
Yes. Both carat per cubic centimeter and stone per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.007451253975 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.
