About Converting Drams per Oil barrel to Imperial hundredweights per Imperial gallon

Dram per Oil barrel 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 oil barrel × 9.972812e-7

This factor comes from each unit's defined relationship to the category's base unit: 1 dram per oil barrel equals 0.011144570993 base units, and 1 imperial hundredweight per imperial gallon equals 11174.9537383 base units, so dividing one by the other gives the direct dram per oil barrel-to-imperial hundredweight per imperial gallon factor of 9.972812e-7.
