About Converting Stones per Cubic Centimeter to Pounds per Cup
Stone per Cubic Centimeter 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 = stones per cubic centimeter × 3312.235311
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per cubic centimeter equals 6350293.18 base units, and 1 pound per cup equals 1917.22283707 base units, so dividing one by the other gives the direct stone per cubic centimeter-to-pound per cup factor of 3312.235311.
Simple example
1 st/cm3 × 3312.235311 = 3,312.235311 lb/cup
1 stone per cubic centimeter = 3,312.235311 pounds per cup.
Real-world example
1,000 st/cm3 × 3312.235311 = 3,312,235.311 lb/cup
1,000 stones per cubic centimeter = 3,312,235.311 pounds per cup.

Frequently asked questions
How many pounds per cup are in 1 stone per cubic centimeter?
1 stone per cubic centimeter equals 3,312.235311 pounds per cup, using the exact defined conversion factor rather than an estimate.
How do I convert stone per cubic centimeter to pound per cup?
Multiply the stone per cubic centimeter value by 3312.235311. The converter above does this instantly to whatever precision you set.
How do I convert pound per cup back to stone per cubic centimeter?
Use the reverse factor: 1 pound per cup equals 0.0003019109 stones per cubic centimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per cubic centimeter?
Stone per Cubic Centimeter (st/cm3) is a unit of density.
What is a pound per cup?
Pound per Cup (lb/cup) is a unit of density.
Is the stone per cubic centimeter to pound per cup conversion exact?
Yes. Both stone per cubic centimeter and pound per cup are defined by fixed standards rather than physical artifacts, so the factor of 3312.235311 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.
