About Converting Ounces per Quart to Pounds per Cup
Ounce per Quart 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 = ounces per quart × 0.015625
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per quart equals 29.9566068292 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct ounce per quart-to-pound per cup factor of 0.015625.
Simple example
1 oz/qt × 0.015625 = 0.015625 lb/cup
1 ounce per quart = 0.015625 pounds per cup.
Real-world example
1,000 oz/qt × 0.015625 = 15.625 lb/cup
1,000 ounces per quart = 15.625 pounds per cup.

What is a ounce per quart?
Ounce per Quart (oz/qt) is a unit of density.
What is a pound per cup?
Pound per Cup (lb/cup) is a unit of density.
Is the ounce per quart to pound per cup conversion exact?
Yes. Both ounce per quart and pound per cup 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.
