About Converting Imperial hundredweights per Oil barrel to Grains per Gallon
Imperial hundredweight per Oil barrel and Grain per 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
grains per gallon = imperial hundredweights per oil barrel × 18666.6666667
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial hundredweight per oil barrel equals 319.537139512 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct imperial hundredweight per oil barrel-to-grain per gallon factor of 18666.6666667.
Simple example
1 long cwt/bbl × 18666.66667 = 18,666.66667 gr/gal
1 imperial hundredweight per oil barrel = 18,666.66667 grains per gallon.
Real-world example
1,000 long cwt/bbl × 18666.66667 = 18,666,666.67 gr/gal
1,000 imperial hundredweights per oil barrel = 18,666,666.67 grains per gallon.
