About Converting Grains per Oil barrel to US hundredweights per Imperial gallon

Grain per Oil barrel and US hundredweight 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

us hundredweights per imperial gallon = grains per oil barrel × 4.084864e-8

This factor comes from each unit's defined relationship to the category's base unit: 1 grain per oil barrel equals 0.00040757288203 base units, and 1 us hundredweight per imperial gallon equals 9977.63726631 base units, so dividing one by the other gives the direct grain per oil barrel-to-us hundredweight per imperial gallon factor of 4.084864e-8.
