About Converting Carats per Fluid ounce to Stones per Gallon
Carat per Fluid ounce 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 fluid ounce × 0.00403130993709
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per fluid ounce equals 6.76280454037 base units, and 1 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct carat per fluid ounce-to-stone per gallon factor of 0.00403130993709.
Simple example
1 ct/fl oz × 0.004031309937 = 0.0040313099 st/gal
1 carat per fluid ounce = 0.0040313099 stones per gallon.
Real-world example
1,000 ct/fl oz × 0.004031309937 = 4.031309937 st/gal
1,000 carats per fluid ounce = 4.031309937 stones per gallon.
