About Converting Drams per Imperial gallon to Grains per Oil barrel
Dram per Imperial gallon and Grain 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
grains per oil barrel = drams per imperial gallon × 956.27425891
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 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct dram per imperial gallon-to-grain per oil barrel factor of 956.27425891.
Simple example
1 dr/imp gal × 956.2742589 = 956.2742589 gr/bbl
1 dram per imperial gallon = 956.2742589 grains per oil barrel.
Real-world example
1,000 dr/imp gal × 956.2742589 = 956,274.2589 gr/bbl
