About Converting Grains per Cup to Imperial hundredweights per Oil barrel
Grain per Cup and Imperial hundredweight 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
imperial hundredweights per oil barrel = grains per cup × 0.000857142857143
This factor comes from each unit's defined relationship to the category's base unit: 1 grain per cup equals 0.273888976724 base units, and 1 imperial hundredweight per oil barrel equals 319.537139512 base units, so dividing one by the other gives the direct grain per cup-to-imperial hundredweight per oil barrel factor of 0.000857142857143.
Simple example
1 gr/cup × 0.0008571428571 = 0.0008571429 long cwt/bbl
1 grain per cup = 0.0008571429 imperial hundredweights per oil barrel.
