About Converting Drams per Cup to Pounds per Quart
Dram per Cup and Pound per Quart 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 quart = drams per cup × 0.015625
This factor comes from each unit's defined relationship to the category's base unit: 1 dram per cup equals 7.48915170731 base units, and 1 pound per quart equals 479.305709268 base units, so dividing one by the other gives the direct dram per cup-to-pound per quart factor of 0.015625.
Simple example
1 dr/cup × 0.015625 = 0.015625 lb/qt
1 dram per cup = 0.015625 pounds per quart.
Real-world example
1,000 dr/cup × 0.015625 = 15.625 lb/qt
1,000 drams per cup = 15.625 pounds per quart.

Frequently asked questions
How many pounds per quart are in 1 dram per cup?
1 dram per cup equals 0.015625 pounds per quart, using the exact defined conversion factor rather than an estimate.
How do I convert dram per cup to pound per quart?
Multiply the dram per cup value by 0.015625. The converter above does this instantly to whatever precision you set.
How do I convert pound per quart back to dram per cup?
Use the reverse factor: 1 pound per quart equals 64 drams per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a dram per cup?
Dram per Cup (dr/cup) is a unit of density.
What is a pound per quart?
Pound per Quart (lb/qt) is a unit of density.
Is the dram per cup to pound per quart conversion exact?
Yes. Both dram per cup and pound per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.015625 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
