About Converting Drams per Gallon to Long tons per Oil barrel
Dram per 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 gallon × 0.0000732421875
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 long ton per oil barrel equals 6390.74279023 base units, so dividing one by the other gives the direct dram per gallon-to-long ton per oil barrel factor of 0.0000732421875.
Simple example
1 dr/gal × 0.0000732421875 = 0.0000732422 long ton/bbl
1 dram per gallon = 0.0000732422 long tons per oil barrel.
Real-world example
1,000 dr/gal × 0.0000732421875 = 0.0732421875 long ton/bbl
1,000 drams per gallon = 0.0732421875 long tons per oil barrel.
