About Converting Drams per Cup to Imperial hundredweights per Imperial gallon
Dram per Cup and Imperial hundredweight 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
imperial hundredweights per imperial gallon = drams per cup × 0.0006701729495
