About Converting Ounces per Cup to Pounds per Cup
Ounce per Cup 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 cup × 0.0625
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cup equals 119.826427317 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct ounce per cup-to-pound per cup factor of 0.0625.
Simple example
1 oz/cup × 0.0625 = 0.0625 lb/cup
1 ounce per cup = 0.0625 pounds per cup.
Real-world example
1,000 oz/cup × 0.0625 = 62.5 lb/cup
1,000 ounces per cup = 62.5 pounds per cup.

Use the reverse factor: 1 pound per cup equals 16 ounces per cup. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per cup?
Ounce per Cup (oz/cup) 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 cup to pound per cup conversion exact?
Yes. Both ounce per cup and pound per cup are defined by fixed standards rather than physical artifacts, so the factor of 0.0625 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.
