About Converting Carats per Gallon to Stones per Fluid ounce
Carat per Gallon 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 gallon × 2.460516e-7
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 fluid ounce equals 214728.957752 base units, so dividing one by the other gives the direct carat per gallon-to-stone per fluid ounce factor of 2.460516e-7.
Simple example
1 ct/gal × 2.460516e-7 = 2.460516e-7 st/fl oz
1 carat per gallon = 2.460516e-7 stones per fluid ounce.
Real-world example
1,000 ct/gal × 2.460516e-7 = 0.0002460516 st/fl oz
1,000 carats per gallon = 0.0002460516 stones per fluid ounce.
