About Converting Carats per Cubic yard to Pounds per Cup
Carat 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 = carats per cubic yard × 1.364422e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic yard equals 0.000261590123863 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct carat per cubic yard-to-pound per cup factor of 1.364422e-7.
Simple example
1 ct/yd3 × 1.364422e-7 = 1.364422e-7 lb/cup
1 carat per cubic yard = 1.364422e-7 pounds per cup.
Real-world example
1,000 ct/yd3 × 1.364422e-7 = 0.0001364422 lb/cup
1,000 carats per cubic yard = 0.0001364422 pounds per cup.
