About Converting Ounces per Cup to Pounds per Cubic Centimeter
Ounce per Cup and Pound per Cubic Centimeter 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 cubic centimeter = ounces per cup × 0.000264172052358
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 cubic centimeter equals 453592.37 base units, so dividing one by the other gives the direct ounce per cup-to-pound per cubic centimeter factor of 0.000264172052358.
Simple example
1 oz/cup × 0.0002641720524 = 0.0002641721 lb/cm3
1 ounce per cup = 0.0002641721 pounds per cubic centimeter.
Real-world example
1,000 oz/cup × 0.0002641720524 = 0.2641720524 lb/cm3
1,000 ounces per cup = 0.2641720524 pounds per cubic centimeter.

What is a ounce per cup?
Ounce per Cup (oz/cup) is a unit of density.
What is a pound per cubic centimeter?
Pound per Cubic Centimeter (lb/cm3) is a unit of density.
Is the ounce per cup to pound per cubic centimeter conversion exact?
Yes. Both ounce per cup and pound per cubic centimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.0002641720524 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.
