About Converting Drams per Oil barrel to Centigrams per Gallon
Dram per Oil barrel and Centigram per Gallon 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
centigrams per gallon = drams per oil barrel × 4.21867903646
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 centigram per gallon equals 0.00264172052358 base units, so dividing one by the other gives the direct dram per oil barrel-to-centigram per gallon factor of 4.21867903646.
Simple example
1 dr/bbl × 4.218679036 = 4.218679036 cg/gal
1 dram per oil barrel = 4.218679036 centigrams per gallon.
Real-world example
1,000 dr/bbl × 4.218679036 = 4,218.679036 cg/gal
1,000 drams per oil barrel = 4,218.679036 centigrams per gallon.
