About Converting Ounces per Oil barrel to Grains per Imperial gallon
Ounce per Oil barrel and Grain per Imperial 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 imperial gallon = ounces per oil barrel × 12.5098950573
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per oil barrel equals 0.178313135888 base units, and 1 grain per imperial gallon equals 0.0142537675233 base units, so dividing one by the other gives the direct ounce per oil barrel-to-grain per imperial gallon factor of 12.5098950573.
Simple example
1 oz/bbl × 12.50989506 = 12.50989506 gr/imp gal
1 ounce per oil barrel = 12.50989506 grains per imperial gallon.
Real-world example
1,000 oz/bbl × 12.50989506 = 12,509.89506 gr/imp gal
1,000 ounces per oil barrel = 12,509.89506 grains per imperial gallon.
