About Converting Carats per Cubic Millimeter to Pounds per Cubic yard
Carat 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 = carats per cubic millimeter × 337110.987111
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic millimeter equals 200000 base units, and 1 pound per cubic yard equals 0.593276421258 base units, so dividing one by the other gives the direct carat per cubic millimeter-to-pound per cubic yard factor of 337110.987111.
Simple example
1 ct/mm3 × 337110.9871 = 337,110.9871 lb/yd3
1 carat per cubic millimeter = 337,110.9871 pounds per cubic yard.
Real-world example
1,000 ct/mm3 × 337110.9871 = 337,110,987.1 lb/yd3
1,000 carats per cubic millimeter = 337,110,987.1 pounds per cubic yard.

Multiply the carat per cubic millimeter value by 337110.9871. The converter above does this instantly to whatever precision you set.
How do I convert pound per cubic yard back to carat per cubic millimeter?
Use the reverse factor: 1 pound per cubic yard equals 0.0000029664 carats per cubic millimeter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic millimeter?
Carat per Cubic Millimeter (ct/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 carat per cubic millimeter to pound per cubic yard conversion exact?
Yes. Both carat per cubic millimeter and pound per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 337110.9871 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.
