About Converting Long tons per Cup to Pounds per Imperial gallon
Long ton per Cup and Pound 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
pounds per imperial gallon = long tons per cup × 43042.0453301
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 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct long ton per cup-to-pound per imperial gallon factor of 43042.0453301.
Simple example
1 long ton/cup × 43042.04533 = 43,042.04533 lb/imp gal
1 long ton per cup = 43,042.04533 pounds per imperial gallon.
Real-world example
1,000 long ton/cup × 43042.04533 = 43,042,045.33 lb/imp gal
1,000 long tons per cup = 43,042,045.33 pounds per imperial gallon.
