About Converting Troy ounces per Oil barrel to Grains per Gallon
Troy ounce 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 = troy ounces per oil barrel × 11.4285714286
This factor comes from each unit's defined relationship to the category's base unit: 1 troy ounce per oil barrel equals 0.195634983375 base units, and 1 grain per gallon equals 0.0171180610453 base units, so dividing one by the other gives the direct troy ounce per oil barrel-to-grain per gallon factor of 11.4285714286.
Simple example
1 oz t/bbl × 11.42857143 = 11.42857143 gr/gal
1 troy ounce per oil barrel = 11.42857143 grains per gallon.
