About Converting Stones per Quart to Kilograms per Liter
Stone per Quart and Kilogram per Liter 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 liter = stones per quart × 6.71027992975
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 liter equals 1000 base units, so dividing one by the other gives the direct stone per quart-to-kilogram per liter factor of 6.71027992975.
Simple example
1 st/qt × 6.71027993 = 6.71027993 kg/L
1 stone per quart = 6.71027993 kilograms per liter.
Real-world example
1,000 st/qt × 6.71027993 = 6,710.27993 kg/L
1,000 stones per quart = 6,710.27993 kilograms per liter.

Mass per volume density.
Understanding the Kilogram per Liter
Kilogram per Liter (kg/L) measures density. Numerically identical to grams per milliliter and to specific gravity for water-based substances, since water has a density of very nearly 1 kg/L. It is classified as a metric derived density unit.
Where it's used: Widely used internationally for fuel, oil, and food-industry density specifications
Uses of the Kilogram per Liter today
- Fuel and petroleum density specifications (diesel is roughly 0.85 kg/L, gasoline roughly 0.74 kg/L)
- Food and beverage industry quality control
- Quick density comparisons against water, since water is almost exactly 1 kg/L

Frequently asked questions
How many kilograms per liter are in 1 stone per quart?
1 stone per quart equals 6.71027993 kilograms per liter, using the exact defined conversion factor rather than an estimate.
How do I convert stone per quart to kilogram per liter?
Multiply the stone per quart value by 6.71027993. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per liter back to stone per quart?
Use the reverse factor: 1 kilogram per liter equals 0.1490250795 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 liter?
Kilogram per Liter (kg/L) measures density. Numerically identical to grams per milliliter and to specific gravity for water-based substances, since water has a density of very nearly 1 kg/L. It is classified as a metric derived density unit.
Is the stone per quart to kilogram per liter conversion exact?
Yes. Both stone per quart and kilogram per liter are defined by fixed standards rather than physical artifacts, so the factor of 6.71027993 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.
