About Converting Slugs per Cup to Long tons per Imperial gallon
Slug 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 = slugs per cup × 0.275995865836
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per cup equals 61684.8206534 base units, and 1 long ton per imperial gallon equals 223499.074765 base units, so dividing one by the other gives the direct slug per cup-to-long ton per imperial gallon factor of 0.275995865836.
