About Converting Nanograms per Cubic Millimeter to Short tons per Cubic yard
Nanogram 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 = nanograms per cubic millimeter × 8.427775e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram per cubic millimeter equals 0.001 base units, and 1 short ton per cubic yard equals 1186.55284252 base units, so dividing one by the other gives the direct nanogram per cubic millimeter-to-short ton per cubic yard factor of 8.427775e-7.
Simple example
1 ng/mm3 × 8.427775e-7 = 8.427775e-7 ton/yd3
1 nanogram per cubic millimeter = 8.427775e-7 short tons per cubic yard.
Real-world example
1,000 ng/mm3 × 8.427775e-7 = 0.0008427775 ton/yd3
1,000 nanograms per cubic millimeter = 0.0008427775 short tons per cubic yard.

Frequently asked questions
How many short tons per cubic yard are in 1 nanogram per cubic millimeter?
1 nanogram per cubic millimeter equals 8.427775e-7 short tons per cubic yard, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per cubic millimeter to short ton per cubic yard?
Multiply the nanogram per cubic millimeter value by 8.427775e-7. The converter above does this instantly to whatever precision you set.
How do I convert short ton per cubic yard back to nanogram per cubic millimeter?
Use the reverse factor: 1 short ton per cubic yard equals 1,186,552.843 nanograms per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanogram per cubic millimeter?
Nanogram per Cubic Millimeter (ng/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 nanogram per cubic millimeter to short ton per cubic yard conversion exact?
Yes. Both nanogram per cubic millimeter and short ton per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 8.427775e-7 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.
