About Converting Drams per Oil barrel to Pounds per Cup
Dram per Oil barrel and Pound per Cup 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 cup = drams per oil barrel × 0.00000581287202381
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per oil barrel equals 0.011144570993 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct dram per oil barrel-to-pound per cup factor of 0.00000581287202381.
Simple example
1 dr/bbl × 0.000005812872024 = 0.0000058129 lb/cup
1 dram per oil barrel = 0.0000058129 pounds per cup.
Real-world example
1,000 dr/bbl × 0.000005812872024 = 0.005812872 lb/cup
1,000 drams per oil barrel = 0.005812872 pounds per cup.
