About Converting Long tons per Cup to Long tons per Imperial gallon
Long ton per Cup and Long ton 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
long tons per imperial gallon = long tons per cup × 19.2151988081
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cup equals 4294579.15504 base units, and 1 long ton per imperial gallon equals 223499.074765 base units, so dividing one by the other gives the direct long ton per cup-to-long ton per imperial gallon factor of 19.2151988081.
