About Converting Pounds per Gallon to Centigrams per Cubic yard
Pound per Gallon and Centigram per Cubic yard 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. Pound per Gallon is most often used for us paint and coatings density specifications.
Formula
centigrams per cubic yard = pounds per gallon × 9161387.712
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per gallon equals 119.826427317 base units, and 1 centigram per cubic yard equals 0.0000130795061931 base units, so dividing one by the other gives the direct pound per gallon-to-centigram per cubic yard factor of 9161387.712.
Simple example
1 lb/gal × 9161387.712 = 9,161,387.712 cg/yd3
1 pound per gallon = 9,161,387.712 centigrams per cubic yard.
Real-world example
1,000 lb/gal × 9161387.712 = 9,161,387,712 cg/yd3
1,000 pounds per gallon = 9,161,387,712 centigrams per cubic yard.

Understanding the Pound per Gallon
Pound per Gallon (lb/gal) measures density. The US customary unit for liquid density, based on the US gallon (231 cubic inches). It is classified as a US customary density unit.
Where it's used: United States (paint, fuel, and industrial liquid density specifications)
lb/gal vs. lb/ft³. Both are US customary density units; they're related through the real, fixed relationship between the US gallon and the cubic foot (1 cubic foot ≈ 7.48 US gallons), not a round conversion factor.
