About Converting Pounds per Cubic yard to Grains per Cubic Centimeter
Pound per Cubic yard and Grain per Cubic Centimeter 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 cubic centimeter = pounds per cubic yard × 0.0091556543352
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 cubic centimeter equals 64.79891 base units, so dividing one by the other gives the direct pound per cubic yard-to-grain per cubic centimeter factor of 0.0091556543352.
Simple example
1 lb/yd3 × 0.009155654335 = 0.0091556543 gr/cm3
1 pound per cubic yard = 0.0091556543 grains per cubic centimeter.
Real-world example
1,000 lb/yd3 × 0.009155654335 = 9.155654335 gr/cm3
1,000 pounds per cubic yard = 9.155654335 grains per cubic centimeter.

Multiply the pound per cubic yard value by 0.009155654335. The converter above does this instantly to whatever precision you set.
How do I convert grain per cubic centimeter back to pound per cubic yard?
Use the reverse factor: 1 grain per cubic centimeter equals 109.2221226 pounds per cubic yard. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per cubic yard?
Pound per Cubic yard (lb/yd3) is a unit of density.
What is a grain per cubic centimeter?
Grain per Cubic Centimeter (gr/cm3) is a unit of density.
Is the pound per cubic yard to grain per cubic centimeter conversion exact?
Yes. Both pound per cubic yard and grain per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.009155654335 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
