About Converting Drams per Imperial gallon to Pounds per Cubic yard
Dram per Imperial gallon and Pound per Cubic yard 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
pounds per cubic yard = drams per imperial gallon × 0.656947489821
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per imperial gallon equals 0.389751455715 base units, and 1 pound per cubic yard equals 0.593276421258 base units, so dividing one by the other gives the direct dram per imperial gallon-to-pound per cubic yard factor of 0.656947489821.
