About Converting Carats per Quart to Kilograms per Cubic yard
Carat per Quart and Kilogram 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
kilograms per cubic yard = carats per quart × 0.161579220779
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per quart equals 0.211337641887 base units, and 1 kilogram per cubic yard equals 1.30795061931 base units, so dividing one by the other gives the direct carat per quart-to-kilogram per cubic yard factor of 0.161579220779.
Simple example
1 ct/qt × 0.1615792208 = 0.1615792208 kg/yd3
1 carat per quart = 0.1615792208 kilograms per cubic yard.
Real-world example
1,000 ct/qt × 0.1615792208 = 161.5792208 kg/yd3
1,000 carats per quart = 161.5792208 kilograms per cubic yard.

What is a carat per quart?
Carat per Quart (ct/qt) is a unit of density.
What is a kilogram per cubic yard?
Kilogram per Cubic yard (kg/yd3) measures density. A mathematically valid way to express bulk material density in kilograms per cubic yard. It is classified as a mixed metric/US customary density unit.
Is the carat per quart to kilogram per cubic yard conversion exact?
Yes. Both carat per quart and kilogram per cubic yard are defined by fixed standards rather than physical artifacts, so the factor of 0.1615792208 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.
