About Converting Long tons per Imperial gallon to Stones per Cup
Long ton per Imperial gallon and Stone 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
stones per cup = long tons per imperial gallon × 8.32674184629
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per imperial gallon equals 223499.074765 base units, and 1 stone per cup equals 26841.119719 base units, so dividing one by the other gives the direct long ton per imperial gallon-to-stone per cup factor of 8.32674184629.
