About Converting Carats per Gallon to Stones per Gallon
Carat per Gallon and Stone per Gallon 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 gallon = carats per gallon × 0.0000314946088836
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 gallon equals 1677.56998244 base units, so dividing one by the other gives the direct carat per gallon-to-stone per gallon factor of 0.0000314946088836.
Simple example
1 ct/gal × 0.00003149460888 = 0.0000314946 st/gal
1 carat per gallon = 0.0000314946 stones per gallon.
Real-world example
1,000 ct/gal × 0.00003149460888 = 0.0314946089 st/gal
1,000 carats per gallon = 0.0314946089 stones per gallon.

What is a carat per gallon?
Carat per Gallon (ct/gal) is a unit of density.
What is a stone per gallon?
Stone per Gallon (st/gal) is a unit of density.
Is the carat per gallon to stone per gallon conversion exact?
