About Converting Pounds per Cubic yard to Pounds per Cup
Pound per Cubic yard and Pound per Cup 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 cup = pounds per cubic yard × 0.000309445730453
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 cup equals 1917.22283707 base units, so dividing one by the other gives the direct pound per cubic yard-to-pound per cup factor of 0.000309445730453.
