About Converting Short tons per Gallon to Long tons per Cup
Short ton per 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 = short tons per gallon × 0.0558035714286
This factor comes from each unit's defined relationship to the category's base unit: 1 short ton per gallon equals 239652.854634 base units, and 1 long ton per cup equals 4294579.15504 base units, so dividing one by the other gives the direct short ton per gallon-to-long ton per cup factor of 0.0558035714286.
