About Converting Grains per Oil barrel to Troy ounces per Gallon
Grain per Oil barrel and Troy ounce 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
troy ounces per gallon = grains per oil barrel × 0.0000496031746032
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 troy ounce per gallon equals 8.21666930173 base units, so dividing one by the other gives the direct grain per oil barrel-to-troy ounce per gallon factor of 0.0000496031746032.
Simple example
1 gr/bbl × 0.0000496031746 = 0.0000496032 oz t/gal
1 grain per oil barrel = 0.0000496032 troy ounces per gallon.
Real-world example
1,000 gr/bbl × 0.0000496031746 = 0.0496031746 oz t/gal
1,000 grains per oil barrel = 0.0496031746 troy ounces per gallon.
