About Converting Pounds per Cubic yard to Pounds per Imperial gallon
Pound per Cubic yard 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 = pounds per cubic yard × 0.00594606123096
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 pound per imperial gallon equals 99.7763726631 base units, so dividing one by the other gives the direct pound per cubic yard-to-pound per imperial gallon factor of 0.00594606123096.
Simple example
1 lb/yd3 × 0.005946061231 = 0.0059460612 lb/imp gal
1 pound per cubic yard = 0.0059460612 pounds per imperial gallon.
Real-world example
1,000 lb/yd3 × 0.005946061231 = 5.946061231 lb/imp gal
1,000 pounds per cubic yard = 5.946061231 pounds per imperial gallon.
