About Converting Pounds per Cubic yard to Carats per Cup
Pound per Cubic yard and Carat 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
carats per cup = pounds per cubic yard × 0.701811111312
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 carat per cup equals 0.845350567546 base units, so dividing one by the other gives the direct pound per cubic yard-to-carat per cup factor of 0.701811111312.
Simple example
1 lb/yd3 × 0.7018111113 = 0.7018111113 ct/cup
