About Converting Nanograms per Cubic Millimeter to Pounds per Cubic yard
Nanogram per Cubic Millimeter and Pound 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
pounds per cubic yard = nanograms per cubic millimeter × 0.00168555493556
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 pound per cubic yard equals 0.593276421258 base units, so dividing one by the other gives the direct nanogram per cubic millimeter-to-pound per cubic yard factor of 0.00168555493556.
Simple example
1 ng/mm3 × 0.001685554936 = 0.0016855549 lb/yd3
1 nanogram per cubic millimeter = 0.0016855549 pounds per cubic yard.
Real-world example
1,000 ng/mm3 × 0.001685554936 = 1.685554936 lb/yd3
1,000 nanograms per cubic millimeter = 1.685554936 pounds per cubic yard.

Frequently asked questions
How many pounds per cubic yard are in 1 nanogram per cubic millimeter?
1 nanogram per cubic millimeter equals 0.0016855549 pounds per cubic yard, using the exact defined conversion factor rather than an estimate.
How do I convert nanogram per cubic millimeter to pound per cubic yard?
Multiply the nanogram per cubic millimeter value by 0.001685554936. The converter above does this instantly to whatever precision you set.
How do I convert pound per cubic yard back to nanogram per cubic millimeter?
Use the reverse factor: 1 pound per cubic yard equals 593.2764213 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 pound per cubic yard?
Pound per Cubic yard (lb/yd3) is a unit of density.
Is the nanogram per cubic millimeter to pound per cubic yard conversion exact?
Yes. Both nanogram per cubic millimeter and pound per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 0.001685554936 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.
