About Converting Milligrams per Cup to Stones per Cubic foot
Milligram per Cup and Stone per Cubic foot 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 cubic foot = milligrams per cup × 0.0000188476828228
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per cup equals 0.00422675283773 base units, and 1 stone per cubic foot equals 224.258487235 base units, so dividing one by the other gives the direct milligram per cup-to-stone per cubic foot factor of 0.0000188476828228.
Simple example
1 mg/cup × 0.00001884768282 = 0.0000188477 st/ft3
1 milligram per cup = 0.0000188477 stones per cubic foot.
Real-world example
1,000 mg/cup × 0.00001884768282 = 0.0188476828 st/ft3
1,000 milligrams per cup = 0.0188476828 stones per cubic foot.

What is a milligram per cup?
Milligram per Cup (mg/cup) is a unit of density.
What is a stone per cubic foot?
Stone per Cubic foot (st/ft3) is a unit of density.
Is the milligram per cup to stone per cubic foot conversion exact?
Yes. Both milligram per cup and stone per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 0.00001884768282 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.
