About Converting Carats per Cubic foot to Stones per Cubic Centimeter
Carat per Cubic foot and Stone 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
stones per cubic centimeter = carats per cubic foot × 1.112222e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic foot equals 0.0070629333443 base units, and 1 stone per cubic centimeter equals 6350293.18 base units, so dividing one by the other gives the direct carat per cubic foot-to-stone per cubic centimeter factor of 1.112222e-9.
Simple example
1 ct/ft3 × 1.112222e-9 = 1.112222e-9 st/cm3
1 carat per cubic foot = 1.112222e-9 stones per cubic centimeter.
Real-world example
1,000 ct/ft3 × 1.112222e-9 = 0.0000011122 st/cm3
1,000 carats per cubic foot = 0.0000011122 stones per cubic centimeter.

Frequently asked questions
How many stones per cubic centimeter are in 1 carat per cubic foot?
1 carat per cubic foot equals 1.112222e-9 stones per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic foot to stone per cubic centimeter?
Multiply the carat per cubic foot value by 1.112222e-9. The converter above does this instantly to whatever precision you set.
How do I convert stone per cubic centimeter back to carat per cubic foot?
Use the reverse factor: 1 stone per cubic centimeter equals 899,101,389 carats per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic foot?
Carat per Cubic foot (ct/ft3) is a unit of density.
What is a stone per cubic centimeter?
Stone per Cubic Centimeter (st/cm3) is a unit of density.
Is the carat per cubic foot to stone per cubic centimeter conversion exact?
Yes. Both carat per cubic foot and stone per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 1.112222e-9 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.
