About Converting Grains per Oil barrel to Troy ounces per Fluid ounce
Grain per Oil barrel and Troy ounce per Fluid ounce 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 fluid ounce = grains per oil barrel × 3.875248e-7
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 fluid ounce equals 1051.73367062 base units, so dividing one by the other gives the direct grain per oil barrel-to-troy ounce per fluid ounce factor of 3.875248e-7.
Simple example
1 gr/bbl × 3.875248e-7 = 3.875248e-7 oz t/fl oz
1 grain per oil barrel = 3.875248e-7 troy ounces per fluid ounce.
Real-world example
1,000 gr/bbl × 3.875248e-7 = 0.0003875248 oz t/fl oz
1,000 grains per oil barrel = 0.0003875248 troy ounces per fluid ounce.
