About Converting Ounces per Cubic Millimeter to Long tons per Cubic yard
Ounce per Cubic Millimeter and Long ton per Cubic yard 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 cubic yard = ounces per cubic millimeter × 21332.4458143
This factor comes from each unit's defined relationship to the category's base unit: 1 ounce per cubic millimeter equals 28349523.125 base units, and 1 long ton per cubic yard equals 1328.93918362 base units, so dividing one by the other gives the direct ounce per cubic millimeter-to-long ton per cubic yard factor of 21332.4458143.
Simple example
1 oz/mm3 × 21332.44581 = 21,332.44581 long ton/yd3
1 ounce per cubic millimeter = 21,332.44581 long tons per cubic yard.
Real-world example
1,000 oz/mm3 × 21332.44581 = 21,332,445.81 long ton/yd3
1,000 ounces per cubic millimeter = 21,332,445.81 long tons per cubic yard.

Frequently asked questions
How many long tons per cubic yard are in 1 ounce per cubic millimeter?
1 ounce per cubic millimeter equals 21,332.44581 long tons per cubic yard, using the exact defined conversion factor rather than an estimate.
How do I convert ounce per cubic millimeter to long ton per cubic yard?
Multiply the ounce per cubic millimeter value by 21332.44581. The converter above does this instantly to whatever precision you set.
How do I convert long ton per cubic yard back to ounce per cubic millimeter?
Use the reverse factor: 1 long ton per cubic yard equals 0.000046877 ounces per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a ounce per cubic millimeter?
Ounce per Cubic Millimeter (oz/mm3) is a unit of density.
What is a long ton per cubic yard?
Long ton per Cubic yard (long ton/yd3) is a unit of density.
Is the ounce per cubic millimeter to long ton per cubic yard conversion exact?
Yes. Both ounce per cubic millimeter and long ton per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 21332.44581 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.
