About Converting Grams per Cubic yard to Kilograms per Quart
Gram 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. Both are mass per volume density units.
Formula
kilograms per quart = grams per cubic yard × 0.00000123778292181
This factor comes from each unit's defined relationship to the category's base unit: 1 gram per cubic yard equals 0.00130795061931 base units, and 1 kilogram per quart equals 1056.68820943 base units, so dividing one by the other gives the direct gram per cubic yard-to-kilogram per quart factor of 0.00000123778292181.
Simple example
1 g/yd3 × 0.000001237782922 = 0.0000012378 kg/qt
1 gram per cubic yard = 0.0000012378 kilograms per quart.
Real-world example
1,000 g/yd3 × 0.000001237782922 = 0.0012377829 kg/qt
1,000 grams per cubic yard = 0.0012377829 kilograms per quart.

Frequently asked questions
How many kilograms per quart are in 1 gram per cubic yard?
1 gram per cubic yard equals 0.0000012378 kilograms per quart, using the exact defined conversion factor rather than an estimate.
How do I convert gram per cubic yard to kilogram per quart?
Multiply the gram per cubic yard value by 0.000001237782922. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per quart back to gram per cubic yard?
Use the reverse factor: 1 kilogram per quart equals 807,896.1039 grams per cubic yard. You can also use the swap control in the converter above to flip the direction instantly.
What is a gram per cubic yard?
Gram per Cubic yard (g/yd3) is a unit of density.
What is a kilogram per quart?
Kilogram per Quart (kg/qt) is a unit of density.
Is the gram per cubic yard to kilogram per quart conversion exact?
Yes. Both gram per cubic yard and kilogram per quart are defined by fixed standards rather than physical artifacts, so the factor of 0.000001237782922 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.
