About Converting Long tons per Cubic yard to Slugs per Cubic Millimeter
Long ton per Cubic yard and Slug 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
slugs per cubic millimeter = long tons per cubic yard × 9.106126e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 long ton per cubic yard equals 1328.93918362 base units, and 1 slug per cubic millimeter equals 14593902937.2 base units, so dividing one by the other gives the direct long ton per cubic yard-to-slug per cubic millimeter factor of 9.106126e-8.
Simple example
1 long ton/yd3 × 9.106126e-8 = 9.106126e-8 slug/mm3
1 long ton per cubic yard = 9.106126e-8 slugs per cubic millimeter.
Real-world example
1,000 long ton/yd3 × 9.106126e-8 = 0.0000910613 slug/mm3
1,000 long tons per cubic yard = 0.0000910613 slugs per cubic millimeter.

Frequently asked questions
How many slugs per cubic millimeter are in 1 long ton per cubic yard?
1 long ton per cubic yard equals 9.106126e-8 slugs per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert long ton per cubic yard to slug per cubic millimeter?
Multiply the long ton per cubic yard value by 9.106126e-8. The converter above does this instantly to whatever precision you set.
How do I convert slug per cubic millimeter back to long ton per cubic yard?
Use the reverse factor: 1 slug per cubic millimeter equals 10,981,618.36 long tons per cubic yard. You can also use the swap control in the converter above to flip the direction instantly.
What is a long ton per cubic yard?
Long ton per Cubic yard (long ton/yd3) is a unit of density.
What is a slug per cubic millimeter?
Slug per Cubic Millimeter (slug/mm3) is a unit of density.
Is the long ton per cubic yard to slug per cubic millimeter conversion exact?
Yes. Both long ton per cubic yard and slug per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 9.106126e-8 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.
