About Converting Slugs per Cup to Pounds per Cubic Millimeter
Slug per Cup and Pound per Cubic Millimeter 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 cubic millimeter = slugs per cup × 0.000135991751037
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per cup equals 61684.8206534 base units, and 1 pound per cubic millimeter equals 453592370 base units, so dividing one by the other gives the direct slug per cup-to-pound per cubic millimeter factor of 0.000135991751037.
Simple example
1 slug/cup × 0.000135991751 = 0.0001359918 lb/mm3
1 slug per cup = 0.0001359918 pounds per cubic millimeter.
Real-world example
1,000 slug/cup × 0.000135991751 = 0.135991751 lb/mm3
1,000 slugs per cup = 0.135991751 pounds per cubic millimeter.

What is a slug per cup?
Slug per Cup (slug/cup) is a unit of density.
What is a pound per cubic millimeter?
Pound per Cubic Millimeter (lb/mm3) is a unit of density.
Is the slug per cup to pound per cubic millimeter conversion exact?
Yes. Both slug per cup and pound per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.000135991751 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.
