About Converting Slugs per Cup to Pounds per Cubic Meter
Slug per Cup and Pound per Cubic Meter 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 meter = slugs per cup × 135991.751037
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 meter equals 0.45359237 base units, so dividing one by the other gives the direct slug per cup-to-pound per cubic meter factor of 135991.751037.
Simple example
1 slug/cup × 135991.751 = 135,991.751 lb/m3
1 slug per cup = 135,991.751 pounds per cubic meter.
Real-world example
1,000 slug/cup × 135991.751 = 135,991,751 lb/m3
1,000 slugs per cup = 135,991,751 pounds per cubic meter.

What is a slug per cup?
Slug per Cup (slug/cup) is a unit of density.
What is a pound per cubic meter?
Pound per Cubic Meter (lb/m3) is a unit of density.
Is the slug per cup to pound per cubic meter conversion exact?
Yes. Both slug per cup and pound per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 135991.751 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.
