About Converting Drams per Imperial gallon to Stones per Oil barrel
Dram per Imperial gallon and Stone 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
stones per oil barrel = drams per imperial gallon × 0.00975790060112
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per imperial gallon equals 0.389751455715 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct dram per imperial gallon-to-stone per oil barrel factor of 0.00975790060112.
Simple example
1 dr/imp gal × 0.009757900601 = 0.0097579006 st/bbl
1 dram per imperial gallon = 0.0097579006 stones per oil barrel.
Real-world example
1,000 dr/imp gal × 0.009757900601 = 9.757900601 st/bbl
1,000 drams per imperial gallon = 9.757900601 stones per oil barrel.
