About Converting Stones per Pint to Carats per Cubic Centimeter
Stone per Pint 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 pint × 67.1027992975
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per pint equals 13420.5598595 base units, and 1 carat per cubic centimeter equals 200 base units, so dividing one by the other gives the direct stone per pint-to-carat per cubic centimeter factor of 67.1027992975.
Simple example
1 st/pt × 67.1027993 = 67.1027993 ct/cm3
1 stone per pint = 67.1027993 carats per cubic centimeter.
Real-world example
1,000 st/pt × 67.1027993 = 67,102.7993 ct/cm3
1,000 stones per pint = 67,102.7993 carats per cubic centimeter.

Frequently asked questions
How many carats per cubic centimeter are in 1 stone per pint?
1 stone per pint equals 67.1027993 carats per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert stone per pint to carat per cubic centimeter?
Multiply the stone per pint value by 67.1027993. The converter above does this instantly to whatever precision you set.
How do I convert carat per cubic centimeter back to stone per pint?
Use the reverse factor: 1 carat per cubic centimeter equals 0.014902508 stones per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per pint?
Stone per Pint (st/pt) 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 pint to carat per cubic centimeter conversion exact?
Yes. Both stone per pint and carat per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 67.1027993 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.
