About Converting Carats per Liter to Stones per Quart
Carat per Liter and Stone per Quart 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 quart = carats per liter × 0.0000298050159001
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per liter equals 0.2 base units, and 1 stone per quart equals 6710.27992975 base units, so dividing one by the other gives the direct carat per liter-to-stone per quart factor of 0.0000298050159001.
Simple example
1 ct/L × 0.0000298050159 = 0.000029805 st/qt
1 carat per liter = 0.000029805 stones per quart.
Real-world example
1,000 ct/L × 0.0000298050159 = 0.0298050159 st/qt
1,000 carats per liter = 0.0298050159 stones per quart.

Frequently asked questions
How many stones per quart are in 1 carat per liter?
1 carat per liter equals 0.000029805 stones per quart, using the exact defined conversion factor rather than an estimate.
How do I convert carat per liter to stone per quart?
Multiply the carat per liter value by 0.0000298050159. The converter above does this instantly to whatever precision you set.
How do I convert stone per quart back to carat per liter?
Use the reverse factor: 1 stone per quart equals 33,551.39965 carats per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per liter?
Carat per Liter (ct/L) is a unit of density.
What is a stone per quart?
Stone per Quart (st/qt) is a unit of density.
Is the carat per liter to stone per quart conversion exact?
Yes. Both carat per liter and stone per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.0000298050159 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.
