About Converting Grams per Cup to Imperial hundredweights per Gallon
Gram per Cup and Imperial hundredweight per 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
imperial hundredweights per gallon = grams per cup × 0.000314946088836
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cup equals 4.22675283773 base units, and 1 imperial hundredweight per gallon equals 13420.5598595 base units, so dividing one by the other gives the direct gram per cup-to-imperial hundredweight per gallon factor of 0.000314946088836.
