About Converting Slugs per Cubic yard to Pounds per Cup
Slug 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 = slugs per cubic yard × 0.00995612195716
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per cubic yard equals 19.0881043849 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct slug per cubic yard-to-pound per cup factor of 0.00995612195716.
Simple example
1 slug/yd3 × 0.009956121957 = 0.009956122 lb/cup
1 slug per cubic yard = 0.009956122 pounds per cup.
Real-world example
1,000 slug/yd3 × 0.009956121957 = 9.956121957 lb/cup
1,000 slugs per cubic yard = 9.956121957 pounds per cup.
