About Converting Drams per Gallon to US hundredweights per Cup
Dram per Gallon and US hundredweight 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
us hundredweights per cup = drams per gallon × 0.00000244140625
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per gallon equals 0.468071981707 base units, and 1 us hundredweight per cup equals 191722.283707 base units, so dividing one by the other gives the direct dram per gallon-to-us hundredweight per cup factor of 0.00000244140625.
