About Converting Stones per Imperial gallon to Pounds per Oil barrel
Stone per Imperial gallon and Pound 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
pounds per oil barrel = stones per imperial gallon × 489.612420562
