About Converting Long tons per Imperial gallon to Slugs per Cup
Long ton per Imperial gallon and Slug 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
slugs per cup = long tons per imperial gallon × 3.62324267783
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 slug per cup equals 61684.8206534 base units, so dividing one by the other gives the direct long ton per imperial gallon-to-slug per cup factor of 3.62324267783.
