About Converting Long tons per Cubic yard to Kilograms per Cubic Millimeter
Long ton per Cubic yard and Kilogram 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
kilograms per cubic millimeter = long tons per cubic yard × 0.00000132893918362
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 kilogram per cubic millimeter equals 1000000000 base units, so dividing one by the other gives the direct long ton per cubic yard-to-kilogram per cubic millimeter factor of 0.00000132893918362.
Simple example
1 long ton/yd3 × 0.000001328939184 = 0.0000013289 kg/mm3
1 long ton per cubic yard = 0.0000013289 kilograms per cubic millimeter.
Real-world example
1,000 long ton/yd3 × 0.000001328939184 = 0.0013289392 kg/mm3
1,000 long tons per cubic yard = 0.0013289392 kilograms per cubic millimeter.

Frequently asked questions
How many kilograms per cubic millimeter are in 1 long ton per cubic yard?
1 long ton per cubic yard equals 0.0000013289 kilograms per cubic millimeter, using the exact defined conversion factor rather than an estimate.
How do I convert long ton per cubic yard to kilogram per cubic millimeter?
Multiply the long ton per cubic yard value by 0.000001328939184. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per cubic millimeter back to long ton per cubic yard?
Use the reverse factor: 1 kilogram per cubic millimeter equals 752,479.8819 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 kilogram per cubic millimeter?
Kilogram per Cubic Millimeter (kg/mm3) is a unit of density.
Is the long ton per cubic yard to kilogram per cubic millimeter conversion exact?
Yes. Both long ton per cubic yard and kilogram per cubic millimeter are defined by fixed standards rather than physical artifacts, so the factor of 0.000001328939184 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.
