About Converting Stones per Quart to Kilograms per Quart
Stone per Quart 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 = stones per quart × 6.35029318
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per quart equals 6710.27992975 base units, and 1 kilogram per quart equals 1056.68820943 base units, so dividing one by the other gives the direct stone per quart-to-kilogram per quart factor of 6.35029318.
Simple example
1 st/qt × 6.35029318 = 6.35029318 kg/qt
1 stone per quart = 6.35029318 kilograms per quart.
Real-world example
1,000 st/qt × 6.35029318 = 6,350.29318 kg/qt
1,000 stones per quart = 6,350.29318 kilograms per quart.

Frequently asked questions
How many kilograms per quart are in 1 stone per quart?
1 stone per quart equals 6.35029318 kilograms per quart, using the exact defined conversion factor rather than an estimate.
How do I convert stone per quart to kilogram per quart?
Multiply the stone per quart value by 6.35029318. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per quart back to stone per quart?
Use the reverse factor: 1 kilogram per quart equals 0.1574730444 stones per quart. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per quart?
Stone per Quart (st/qt) is a unit of density.
What is a kilogram per quart?
Kilogram per Quart (kg/qt) is a unit of density.
Is the stone per quart to kilogram per quart conversion exact?
Yes. Both stone per quart and kilogram per quart are defined by fixed standards rather than physical artifacts, so the factor of 6.35029318 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.
