About Converting Stones per Cup to Carats per Imperial gallon
Stone per Cup and Carat 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
carats per imperial gallon = stones per cup × 610110.729716
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cup equals 26841.119719 base units, and 1 carat per imperial gallon equals 0.0439938496598 base units, so dividing one by the other gives the direct stone per cup-to-carat per imperial gallon factor of 610110.729716.
Simple example
1 st/cup × 610110.7297 = 610,110.7297 ct/imp gal
1 stone per cup = 610,110.7297 carats per imperial gallon.
Real-world example
1,000 st/cup × 610110.7297 = 610,110,729.7 ct/imp gal
1,000 stones per cup = 610,110,729.7 carats per imperial gallon.

What is a stone per cup?
Stone per Cup (st/cup) is a unit of density.
What is a carat per imperial gallon?
Carat per Imperial gallon (ct/imp gal) is a unit of density.
Is the stone per cup to carat per imperial gallon conversion exact?
Yes. Both stone per cup and carat per imperial gallon are defined by fixed standards rather than physical artifacts, so the factor of 610110.7297 used above is exact to as many digits as you choose to display.
