About Converting Pounds per Imperial gallon to Grams per Cup
Pound per Imperial gallon and Gram 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
grams per cup = pounds per imperial gallon × 23.6059160527
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 gram per cup equals 4.22675283773 base units, so dividing one by the other gives the direct pound per imperial gallon-to-gram per cup factor of 23.6059160527.
