About Converting Drams per Gallon to Pounds per Oil barrel
Dram per Gallon and Pound 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
pounds per oil barrel = drams per gallon × 0.1640625
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 pound per oil barrel equals 2.85301017421 base units, so dividing one by the other gives the direct dram per gallon-to-pound per oil barrel factor of 0.1640625.
Simple example
1 dr/gal × 0.1640625 = 0.1640625 lb/bbl
1 dram per gallon = 0.1640625 pounds per oil barrel.
Real-world example
1,000 dr/gal × 0.1640625 = 164.0625 lb/bbl
1,000 drams per gallon = 164.0625 pounds per oil barrel.
