About Converting Carats per Cubic Millimeter to Stones per Pint
Carat per Cubic Millimeter and Stone per Pint 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 pint = carats per cubic millimeter × 14.90250795
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic millimeter equals 200000 base units, and 1 stone per pint equals 13420.5598595 base units, so dividing one by the other gives the direct carat per cubic millimeter-to-stone per pint factor of 14.90250795.
Simple example
1 ct/mm3 × 14.90250795 = 14.90250795 st/pt
1 carat per cubic millimeter = 14.90250795 stones per pint.
Real-world example
1,000 ct/mm3 × 14.90250795 = 14,902.50795 st/pt
1,000 carats per cubic millimeter = 14,902.50795 stones per pint.

Frequently asked questions
How many stones per pint are in 1 carat per cubic millimeter?
1 carat per cubic millimeter equals 14.90250795 stones per pint, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic millimeter to stone per pint?
Multiply the carat per cubic millimeter value by 14.90250795. The converter above does this instantly to whatever precision you set.
How do I convert stone per pint back to carat per cubic millimeter?
Use the reverse factor: 1 stone per pint equals 0.0671027993 carats per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic millimeter?
Carat per Cubic Millimeter (ct/mm3) is a unit of density.
What is a stone per pint?
Stone per Pint (st/pt) is a unit of density.
Is the carat per cubic millimeter to stone per pint conversion exact?
Yes. Both carat per cubic millimeter and stone per pint are defined by fixed standards rather than physical artifacts, so the factor of 14.90250795 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.
