About Converting Drams per Cubic yard to Pounds per Cup
Dram 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 = drams per cubic yard × 0.00000120877238458
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cubic yard equals 0.00231748602054 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct dram per cubic yard-to-pound per cup factor of 0.00000120877238458.
Simple example
1 dr/yd3 × 0.000001208772385 = 0.0000012088 lb/cup
1 dram per cubic yard = 0.0000012088 pounds per cup.
Real-world example
1,000 dr/yd3 × 0.000001208772385 = 0.0012087724 lb/cup
1,000 drams per cubic yard = 0.0012087724 pounds per cup.
