About Converting Carats per Gallon to Stones per Imperial gallon
Carat per Gallon and Stone per Imperial 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 imperial gallon = carats per gallon × 0.0000378234481925
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 imperial gallon equals 1396.86921728 base units, so dividing one by the other gives the direct carat per gallon-to-stone per imperial gallon factor of 0.0000378234481925.
Simple example
1 ct/gal × 0.00003782344819 = 0.0000378234 st/imp gal
1 carat per gallon = 0.0000378234 stones per imperial gallon.
Real-world example
1,000 ct/gal × 0.00003782344819 = 0.0378234482 st/imp gal
1,000 carats per gallon = 0.0378234482 stones per imperial gallon.
