About Converting Pounds per Imperial gallon to Long tons per Oil barrel
Pound per Imperial gallon and Long ton 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
long tons per oil barrel = pounds per imperial gallon × 0.0156126409618
