About Converting US hundredweights per Gallon to Grains per Oil barrel
US hundredweight per Gallon and Grain 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
grains per oil barrel = us hundredweights per gallon × 29400000
This factor comes from each unit's defined relationship to the category's base unit: 1 us hundredweight per gallon equals 11982.6427317 base units, and 1 grain per oil barrel equals 0.00040757288203 base units, so dividing one by the other gives the direct us hundredweight per gallon-to-grain per oil barrel factor of 29400000.
Simple example
1 cwt/gal × 29400000 = 29,400,000 gr/bbl
1 us hundredweight per gallon = 29,400,000 grains per oil barrel.
Real-world example
1,000 cwt/gal × 29400000 = 29,400,000,000 gr/bbl
1,000 us hundredweights per gallon = 29,400,000,000 grains per oil barrel.
