About Converting Carats per Gallon to Stones per Quart
Carat per Gallon 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 gallon × 0.00000787365222089
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per gallon equals 0.0528344104716 base units, and 1 stone per quart equals 6710.27992975 base units, so dividing one by the other gives the direct carat per gallon-to-stone per quart factor of 0.00000787365222089.
Simple example
1 ct/gal × 0.000007873652221 = 0.0000078737 st/qt
1 carat per gallon = 0.0000078737 stones per quart.
Real-world example
1,000 ct/gal × 0.000007873652221 = 0.0078736522 st/qt
1,000 carats per gallon = 0.0078736522 stones per quart.

What is a carat per gallon?
Carat per Gallon (ct/gal) 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 gallon to stone per quart conversion exact?
Yes. Both carat per gallon and stone per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.000007873652221 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.
