About Converting Pounds per Cup to Decigrams per Imperial gallon
Pound per Cup and Decigram 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
decigrams per imperial gallon = pounds per cup × 87158.6756738
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cup equals 1917.22283707 base units, and 1 decigram per imperial gallon equals 0.0219969248299 base units, so dividing one by the other gives the direct pound per cup-to-decigram per imperial gallon factor of 87158.6756738.
