About Converting Drams per Quart to Imperial hundredweights per Gallon
Dram per Quart 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 = drams per quart × 0.000139508928571
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per quart equals 1.87228792683 base units, and 1 imperial hundredweight per gallon equals 13420.5598595 base units, so dividing one by the other gives the direct dram per quart-to-imperial hundredweight per gallon factor of 0.000139508928571.
Simple example
1 dr/qt × 0.0001395089286 = 0.0001395089 long cwt/gal
1 dram per quart = 0.0001395089 imperial hundredweights per gallon.
