About Converting Slugs per Cubic Millimeter to Long tons per Cup
Slug per Cubic Millimeter and Long ton 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
long tons per cup = slugs per cubic millimeter × 3398.21491474
This factor comes from each unit's defined relationship to the category's base unit: 1 slug per cubic millimeter equals 14593902937.2 base units, and 1 long ton per cup equals 4294579.15504 base units, so dividing one by the other gives the direct slug per cubic millimeter-to-long ton per cup factor of 3398.21491474.
Simple example
1 slug/mm3 × 3398.214915 = 3,398.214915 long ton/cup
1 slug per cubic millimeter = 3,398.214915 long tons per cup.
Real-world example
1,000 slug/mm3 × 3398.214915 = 3,398,214.915 long ton/cup
1,000 slugs per cubic millimeter = 3,398,214.915 long tons per cup.

Frequently asked questions
How many long tons per cup are in 1 slug per cubic millimeter?
1 slug per cubic millimeter equals 3,398.214915 long tons per cup, using the exact defined conversion factor rather than an estimate.
How do I convert slug per cubic millimeter to long ton per cup?
Multiply the slug per cubic millimeter value by 3398.214915. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cup back to slug per cubic millimeter?
Use the reverse factor: 1 long ton per cup equals 0.0002942721 slugs per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a slug per cubic millimeter?
Slug per Cubic Millimeter (slug/mm3) is a unit of density.
What is a long ton per cup?
Long ton per Cup (long ton/cup) is a unit of density.
Is the slug per cubic millimeter to long ton per cup conversion exact?
Yes. Both slug per cubic millimeter and long ton per cup are defined by fixed standards rather than physical artifacts, so the factor of 3398.214915 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.
