About Converting Long tons per Cup to Slugs per Imperial gallon
Long ton per Cup and Slug 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
slugs per imperial gallon = long tons per cup × 1337.78766619
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cup equals 4294579.15504 base units, and 1 slug per imperial gallon equals 3210.20985885 base units, so dividing one by the other gives the direct long ton per cup-to-slug per imperial gallon factor of 1337.78766619.
Simple example
1 long ton/cup × 1337.787666 = 1,337.787666 slug/imp gal
1 long ton per cup = 1,337.787666 slugs per imperial gallon.
