About Converting Carats per Cubic Millimeter to Pounds per Quart
Carat per Cubic Millimeter and Pound per Quart 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 quart = carats per cubic millimeter × 417.270222601
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 quart equals 479.305709268 base units, so dividing one by the other gives the direct carat per cubic millimeter-to-pound per quart factor of 417.270222601.
Simple example
1 ct/mm3 × 417.2702226 = 417.2702226 lb/qt
1 carat per cubic millimeter = 417.2702226 pounds per quart.
Real-world example
1,000 ct/mm3 × 417.2702226 = 417,270.2226 lb/qt
1,000 carats per cubic millimeter = 417,270.2226 pounds per quart.

Frequently asked questions
How many pounds per quart are in 1 carat per cubic millimeter?
1 carat per cubic millimeter equals 417.2702226 pounds per quart, using the exact defined conversion factor rather than an estimate.
How do I convert carat per cubic millimeter to pound per quart?
Multiply the carat per cubic millimeter value by 417.2702226. The converter above does this instantly to whatever precision you set.
How do I convert pound per quart back to carat per cubic millimeter?
Use the reverse factor: 1 pound per quart equals 0.0023965285 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 quart?
Pound per Quart (lb/qt) is a unit of density.
Is the carat per cubic millimeter to pound per quart conversion exact?
Yes. Both carat per cubic millimeter and pound per quart are defined by fixed standards rather than physical artifacts, so the factor of 417.2702226 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.
