About Converting Milligrams per Cubic Millimeter to Short tons per Cubic yard
Milligram per Cubic Millimeter and Short 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
short tons per cubic yard = milligrams per cubic millimeter × 0.842777467778
This factor comes from each unit's defined relationship to the category's base unit: 1 milligram per cubic millimeter equals 1000 base units, and 1 short ton per cubic yard equals 1186.55284252 base units, so dividing one by the other gives the direct milligram per cubic millimeter-to-short ton per cubic yard factor of 0.842777467778.
Simple example
1 mg/mm3 × 0.8427774678 = 0.8427774678 ton/yd3
1 milligram per cubic millimeter = 0.8427774678 short tons per cubic yard.
Real-world example
1,000 mg/mm3 × 0.8427774678 = 842.7774678 ton/yd3
1,000 milligrams per cubic millimeter = 842.7774678 short tons per cubic yard.

Frequently asked questions
How many short tons per cubic yard are in 1 milligram per cubic millimeter?
1 milligram per cubic millimeter equals 0.8427774678 short tons per cubic yard, using the exact defined conversion factor rather than an estimate.
How do I convert milligram per cubic millimeter to short ton per cubic yard?
Multiply the milligram per cubic millimeter value by 0.8427774678. The converter above does this instantly to whatever precision you set.
How do I convert short ton per cubic yard back to milligram per cubic millimeter?
Use the reverse factor: 1 short ton per cubic yard equals 1.186552843 milligrams per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a milligram per cubic millimeter?
Milligram per Cubic Millimeter (mg/mm3) is a unit of density.
What is a short ton per cubic yard?
Short ton per Cubic yard (ton/yd3) is a unit of density.
Is the milligram per cubic millimeter to short ton per cubic yard conversion exact?
Yes. Both milligram per cubic millimeter and short ton per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 0.8427774678 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.
