About Converting Stones per Oil barrel to Long tons per Imperial gallon
Stone per Oil barrel and Long ton per Imperial gallon 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
long tons per imperial gallon = stones per oil barrel × 0.000178712786533
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per oil barrel equals 39.942142439 base units, and 1 long ton per imperial gallon equals 223499.074765 base units, so dividing one by the other gives the direct stone per oil barrel-to-long ton per imperial gallon factor of 0.000178712786533.
