About Converting Carat per Cubic inches to Pounds per Cubic yard
Carat per Cubic inch and Pound 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. Both are mass per volume density units.
Formula
pounds per cubic yard = carat per cubic inches × 20.571774609
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic inch equals 12.2047488189 base units, and 1 pound per cubic yard equals 0.593276421258 base units, so dividing one by the other gives the direct carat per cubic inch-to-pound per cubic yard factor of 20.571774609.
