About Converting Drams per Imperial gallon to Long tons per Oil barrel
Dram per Imperial gallon and Long ton 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
long tons per oil barrel = drams per imperial gallon × 0.000060986878757
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 long ton per oil barrel equals 6390.74279023 base units, so dividing one by the other gives the direct dram per imperial gallon-to-long ton per oil barrel factor of 0.000060986878757.
