About Converting Carats per Imperial gallon to Long tons per Cup
Carat per Imperial gallon and Long ton per Cup 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
long tons per cup = carats per imperial gallon × 1.024404e-8
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 long ton per cup equals 4294579.15504 base units, so dividing one by the other gives the direct carat per imperial gallon-to-long ton per cup factor of 1.024404e-8.
Simple example
1 ct/imp gal × 1.024404e-8 = 1.024404e-8 long ton/cup
1 carat per imperial gallon = 1.024404e-8 long tons per cup.
