About Converting Stones per Imperial gallon to Stones per Oil barrel
Stone 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 = stones per imperial gallon × 34.9723157544
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 stone per oil barrel equals 39.942142439 base units, so dividing one by the other gives the direct stone per imperial gallon-to-stone per oil barrel factor of 34.9723157544.
Simple example
1 st/imp gal × 34.97231575 = 34.97231575 st/bbl
1 stone per imperial gallon = 34.97231575 stones per oil barrel.
