About Converting Grains per Oil barrel to Pounds per Imperial gallon
Grain per Oil barrel and Pound 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
pounds per imperial gallon = grains per oil barrel × 0.00000408486369219
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 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct grain per oil barrel-to-pound per imperial gallon factor of 0.00000408486369219.
Simple example
1 gr/bbl × 0.000004084863692 = 0.0000040849 lb/imp gal
1 grain per oil barrel = 0.0000040849 pounds per imperial gallon.
Real-world example
1,000 gr/bbl × 0.000004084863692 = 0.0040848637 lb/imp gal
1,000 grains per oil barrel = 0.0040848637 pounds per imperial gallon.
