About Converting Drams per Imperial gallon to Imperial hundredweights per Cup
Dram per Imperial gallon and Imperial 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
imperial hundredweights per cup = drams per imperial gallon × 0.00000181508567729
