About Converting Pounds per Oil barrel to Drams per Imperial gallon
Pound per Oil barrel and Dram 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
drams per imperial gallon = pounds per oil barrel × 7.32007573641
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per oil barrel equals 2.85301017421 base units, and 1 dram per imperial gallon equals 0.389751455715 base units, so dividing one by the other gives the direct pound per oil barrel-to-dram per imperial gallon factor of 7.32007573641.
