About Converting Drams per Gallon to US hundredweights per Oil barrel
Dram per Gallon and US hundredweight per Oil barrel 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 oil barrel = drams per gallon × 0.001640625
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 oil barrel equals 285.301017421 base units, so dividing one by the other gives the direct dram per gallon-to-us hundredweight per oil barrel factor of 0.001640625.
