About Converting Grains per Imperial gallon to Stones per Oil barrel
Grain 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 = grains per imperial gallon × 0.000356860364841
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per imperial gallon equals 0.0142537675233 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct grain per imperial gallon-to-stone per oil barrel factor of 0.000356860364841.
Simple example
1 gr/imp gal × 0.0003568603648 = 0.0003568604 st/bbl
1 grain per imperial gallon = 0.0003568604 stones per oil barrel.
Real-world example
1,000 gr/imp gal × 0.0003568603648 = 0.3568603648 st/bbl
1,000 grains per imperial gallon = 0.3568603648 stones per oil barrel.
