About Converting Pounds per Cubic yard to Grains per Imperial gallon
Pound per Cubic yard 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 = pounds per cubic yard × 41.6224286167
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic yard equals 0.593276421258 base units, and 1 grain per imperial gallon equals 0.0142537675233 base units, so dividing one by the other gives the direct pound per cubic yard-to-grain per imperial gallon factor of 41.6224286167.
Simple example
1 lb/yd3 × 41.62242862 = 41.62242862 gr/imp gal
1 pound per cubic yard = 41.62242862 grains per imperial gallon.
Real-world example
1,000 lb/yd3 × 41.62242862 = 41,622.42862 gr/imp gal
1,000 pounds per cubic yard = 41,622.42862 grains per imperial gallon.
