About Converting Dram per Cubic inches to Pounds per Oil barrel
Dram per Cubic inch 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 = dram per cubic inches × 37.8984375
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic inch equals 108.124627774 base units, and 1 pound per oil barrel equals 2.85301017421 base units, so dividing one by the other gives the direct dram per cubic inch-to-pound per oil barrel factor of 37.8984375.
Simple example
1 dr/in3 × 37.8984375 = 37.8984375 lb/bbl
1 dram per cubic inch = 37.8984375 pounds per oil barrel.
