About Converting Drams per Gallon to US hundredweights per Imperial gallon
Dram per Gallon and US 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
us hundredweights per imperial gallon = drams per gallon × 0.000046912106465
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per gallon equals 0.468071981707 base units, and 1 us hundredweight per imperial gallon equals 9977.63726631 base units, so dividing one by the other gives the direct dram per gallon-to-us hundredweight per imperial gallon factor of 0.000046912106465.
