About Converting Pounds per Imperial gallon to Carats per Cup
Pound per Imperial gallon and Carat 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
carats per cup = pounds per imperial gallon × 118.029580264
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 carat per cup equals 0.845350567546 base units, so dividing one by the other gives the direct pound per imperial gallon-to-carat per cup factor of 118.029580264.
