About Converting Carats per Quart to Stones per Cubic Centimeter
Carat per Quart 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 quart × 3.327998e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per quart equals 0.211337641887 base units, and 1 stone per cubic centimeter equals 6350293.18 base units, so dividing one by the other gives the direct carat per quart-to-stone per cubic centimeter factor of 3.327998e-8.
Simple example
1 ct/qt × 3.327998e-8 = 3.327998e-8 st/cm3
1 carat per quart = 3.327998e-8 stones per cubic centimeter.
Real-world example
1,000 ct/qt × 3.327998e-8 = 0.00003328 st/cm3
1,000 carats per quart = 0.00003328 stones per cubic centimeter.

Frequently asked questions
How many stones per cubic centimeter are in 1 carat per quart?
1 carat per quart equals 3.327998e-8 stones per cubic centimeter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per quart to stone per cubic centimeter?
Multiply the carat per quart value by 3.327998e-8. The converter above does this instantly to whatever precision you set.
How do I convert stone per cubic centimeter back to carat per quart?
Use the reverse factor: 1 stone per cubic centimeter equals 30,048,093.29 carats per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per quart?
Carat per Quart (ct/qt) 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 quart to stone per cubic centimeter conversion exact?
Yes. Both carat per quart and stone per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 3.327998e-8 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.
