About Converting Kilograms per Cup to Pounds per Imperial gallon
Kilogram 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 = kilograms per cup × 42.3622619756
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cup equals 4226.75283773 base units, and 1 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct kilogram per cup-to-pound per imperial gallon factor of 42.3622619756.
