About Converting Carats per Imperial gallon to Stones per Gallon
Carat per Imperial 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 imperial gallon × 0.0000262247477723
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per imperial gallon equals 0.0439938496598 base units, and 1 stone per gallon equals 1677.56998244 base units, so dividing one by the other gives the direct carat per imperial gallon-to-stone per gallon factor of 0.0000262247477723.
Simple example
1 ct/imp gal × 0.00002622474777 = 0.0000262247 st/gal
1 carat per imperial gallon = 0.0000262247 stones per gallon.
Real-world example
1,000 ct/imp gal × 0.00002622474777 = 0.0262247478 st/gal
1,000 carats per imperial gallon = 0.0262247478 stones per gallon.
