About Converting Pounds per Cubic Centimeter to Stones per Cup
Pound per Cubic Centimeter and Stone 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
stones per cup = pounds per cubic centimeter × 16.89915975
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic centimeter equals 453592.37 base units, and 1 stone per cup equals 26841.119719 base units, so dividing one by the other gives the direct pound per cubic centimeter-to-stone per cup factor of 16.89915975.
Simple example
1 lb/cm3 × 16.89915975 = 16.89915975 st/cup
1 pound per cubic centimeter = 16.89915975 stones per cup.
Real-world example
1,000 lb/cm3 × 16.89915975 = 16,899.15975 st/cup
1,000 pounds per cubic centimeter = 16,899.15975 stones per cup.

What is a pound per cubic centimeter?
Pound per Cubic Centimeter (lb/cm3) is a unit of density.
What is a stone per cup?
Stone per Cup (st/cup) is a unit of density.
Is the pound per cubic centimeter to stone per cup conversion exact?
Yes. Both pound per cubic centimeter and stone per cup are defined by fixed standards rather than physical artifacts, so the factor of 16.89915975 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.
