About Converting Imperial hundredweights per Oil barrel to Drams per Cup
Imperial hundredweight per Oil barrel and Dram 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
drams per cup = imperial hundredweights per oil barrel × 42.6666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial hundredweight per oil barrel equals 319.537139512 base units, and 1 dram per cup equals 7.48915170731 base units, so dividing one by the other gives the direct imperial hundredweight per oil barrel-to-dram per cup factor of 42.6666666667.
Simple example
1 long cwt/bbl × 42.66666667 = 42.66666667 dr/cup
1 imperial hundredweight per oil barrel = 42.66666667 drams per cup.
