About Converting Kilograms per Cubic yard to Kilograms per Quart
Kilogram per Cubic yard 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. Kilogram per Cubic yard is most often used for can be used to express the density of bulk construction materials such as gravel, soil, or aggregate — in practice, us construction and landscaping references more commonly express this as tons per cubic yard or pounds per cubic foot.
Formula
kilograms per quart = kilograms per cubic yard × 0.00123778292181
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram per cubic yard equals 1.30795061931 base units, and 1 kilogram per quart equals 1056.68820943 base units, so dividing one by the other gives the direct kilogram per cubic yard-to-kilogram per quart factor of 0.00123778292181.
Simple example
1 kg/yd3 × 0.001237782922 = 0.0012377829 kg/qt
1 kilogram per cubic yard = 0.0012377829 kilograms per quart.
Real-world example
1,000 kg/yd3 × 0.001237782922 = 1.237782922 kg/qt
1,000 kilograms per cubic yard = 1.237782922 kilograms per quart.

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.
What is a kilogram per quart?
Kilogram per Quart (kg/qt) is a unit of density.
Is the kilogram per cubic yard to kilogram per quart conversion exact?
Yes. Both kilogram per cubic yard and kilogram per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.001237782922 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.
