About Converting Long tons per Gallon to Short tons per Imperial gallon
Long ton per Gallon and Short 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
short tons per imperial gallon = long tons per gallon × 1.34506391657
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per gallon equals 268411.19719 base units, and 1 short ton per imperial gallon equals 199552.745326 base units, so dividing one by the other gives the direct long ton per gallon-to-short ton per imperial gallon factor of 1.34506391657.
