About Converting Pounds per Imperial gallon to Stones per Oil barrel
Pound 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 = pounds per imperial gallon × 2.49802255389
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per imperial gallon equals 99.7763726631 base units, and 1 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct pound per imperial gallon-to-stone per oil barrel factor of 2.49802255389.
