About Converting Carats per Cubic foot to Kilograms per Quart
Carat per Cubic foot and Kilogram 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
kilograms per quart = carats per cubic foot × 0.00000668402777778
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per cubic foot equals 0.0070629333443 base units, and 1 kilogram per quart equals 1056.68820943 base units, so dividing one by the other gives the direct carat per cubic foot-to-kilogram per quart factor of 0.00000668402777778.
Simple example
1 ct/ft3 × 0.000006684027778 = 0.000006684 kg/qt
1 carat per cubic foot = 0.000006684 kilograms per quart.
Real-world example
1,000 ct/ft3 × 0.000006684027778 = 0.0066840278 kg/qt
1,000 carats per cubic foot = 0.0066840278 kilograms per quart.

Multiply the carat per cubic foot value by 0.000006684027778. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per quart back to carat per cubic foot?
Use the reverse factor: 1 kilogram per quart equals 149,610.3896 carats per cubic foot. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per cubic foot?
Carat per Cubic foot (ct/ft3) is a unit of density.
What is a kilogram per quart?
Kilogram per Quart (kg/qt) is a unit of density.
Is the carat per cubic foot to kilogram per quart conversion exact?
Yes. Both carat per cubic foot and kilogram per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.000006684027778 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.
