About Converting Stones per Cup to Carats per Cubic Centimeter
Stone per Cup and Carat per Cubic Centimeter 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 cubic centimeter = stones per cup × 134.205598595
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cup equals 26841.119719 base units, and 1 carat per cubic centimeter equals 200 base units, so dividing one by the other gives the direct stone per cup-to-carat per cubic centimeter factor of 134.205598595.
Simple example
1 st/cup × 134.2055986 = 134.2055986 ct/cm3
1 stone per cup = 134.2055986 carats per cubic centimeter.
Real-world example
1,000 st/cup × 134.2055986 = 134,205.5986 ct/cm3
1,000 stones per cup = 134,205.5986 carats per cubic centimeter.

Frequently asked questions
How many carats per cubic centimeter are in 1 stone per cup?
1 stone per cup equals 134.2055986 carats per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert stone per cup to carat per cubic centimeter?
Multiply the stone per cup value by 134.2055986. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic centimeter back to stone per cup?
Use the reverse factor: 1 carat per cubic centimeter equals 0.007451254 stones per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per cup?
Stone per Cup (st/cup) is a unit of density.
What is a carat per cubic centimeter?
Carat per Cubic Centimeter (ct/cm3) is a unit of density.
Is the stone per cup to carat per cubic centimeter conversion exact?
Yes. Both stone per cup and carat per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 134.2055986 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.
