About Converting Stones per Imperial gallon to Drams per Oil barrel
Stone 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 = stones per imperial gallon × 125340.779664
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per imperial gallon equals 1396.86921728 base units, and 1 dram per oil barrel equals 0.011144570993 base units, so dividing one by the other gives the direct stone per imperial gallon-to-dram per oil barrel factor of 125340.779664.
Simple example
1 st/imp gal × 125340.7797 = 125,340.7797 dr/bbl
1 stone per imperial gallon = 125,340.7797 drams per oil barrel.
Real-world example
