About Converting Pounds per Cubic Millimeter to Slugs per Cup
Pound per Cubic Millimeter 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 = pounds per cubic millimeter × 7353.38718984
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic millimeter equals 453592370 base units, and 1 slug per cup equals 61684.8206534 base units, so dividing one by the other gives the direct pound per cubic millimeter-to-slug per cup factor of 7353.38718984.
Simple example
1 lb/mm3 × 7353.38719 = 7,353.38719 slug/cup
1 pound per cubic millimeter = 7,353.38719 slugs per cup.
Real-world example
1,000 lb/mm3 × 7353.38719 = 7,353,387.19 slug/cup
1,000 pounds per cubic millimeter = 7,353,387.19 slugs per cup.

What is a pound per cubic millimeter?
Pound per Cubic Millimeter (lb/mm3) is a unit of density.
What is a slug per cup?
Slug per Cup (slug/cup) is a unit of density.
Is the pound per cubic millimeter to slug per cup conversion exact?
Yes. Both pound per cubic millimeter and slug per cup are defined by fixed standards rather than physical artifacts, so the factor of 7353.38719 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.
