About Converting Carats per Fluid ounce to Stones per Fluid ounce
Carat per Fluid ounce and Stone per Fluid ounce 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 fluid ounce = carats per fluid ounce × 0.0000314946088836
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 fluid ounce equals 214728.957752 base units, so dividing one by the other gives the direct carat per fluid ounce-to-stone per fluid ounce factor of 0.0000314946088836.
Simple example
1 ct/fl oz × 0.00003149460888 = 0.0000314946 st/fl oz
