About Converting Milligrams per Cubic foot to Slugs per Cup
Milligram per Cubic foot and Slug 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
slugs per cup = milligrams per cubic foot × 5.725017e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per cubic foot equals 0.0000353146667215 base units, and 1 slug per cup equals 61684.8206534 base units, so dividing one by the other gives the direct milligram per cubic foot-to-slug per cup factor of 5.725017e-10.
Simple example
1 mg/ft3 × 5.725017e-10 = 5.725017e-10 slug/cup
1 milligram per cubic foot = 5.725017e-10 slugs per cup.
Real-world example
1,000 mg/ft3 × 5.725017e-10 = 5.725017e-7 slug/cup
1,000 milligrams per cubic foot = 5.725017e-7 slugs per cup.

What is a milligram per cubic foot?
Milligram per Cubic foot (mg/ft3) is a unit of density.
What is a slug per cup?
Slug per Cup (slug/cup) is a unit of density.
Is the milligram per cubic foot to slug per cup conversion exact?
Yes. Both milligram per cubic foot and slug per cup are defined by fixed standards rather than physical artifacts, so the factor of 5.725017e-10 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.
