About Converting Milligrams per Imperial gallon to Drams per Oil barrel
Milligram per Imperial gallon and Dram 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
drams per oil barrel = milligrams per imperial gallon × 0.0197377941634
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per imperial gallon equals 0.000219969248299 base units, and 1 dram per oil barrel equals 0.011144570993 base units, so dividing one by the other gives the direct milligram per imperial gallon-to-dram per oil barrel factor of 0.0197377941634.
Simple example
1 mg/imp gal × 0.01973779416 = 0.0197377942 dr/bbl
1 milligram per imperial gallon = 0.0197377942 drams per oil barrel.
Real-world example
1,000 mg/imp gal × 0.01973779416 = 19.73779416 dr/bbl
1,000 milligrams per imperial gallon = 19.73779416 drams per oil barrel.
