About Converting Stones per Liter to Kilograms per Liter
Stone per Liter 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 liter × 6.35029318
This factor comes from each unit's defined relationship to the category's base unit: 1 stone per liter equals 6350.29318 base units, and 1 kilogram per liter equals 1000 base units, so dividing one by the other gives the direct stone per liter-to-kilogram per liter factor of 6.35029318.
Simple example
1 st/L × 6.35029318 = 6.35029318 kg/L
1 stone per liter = 6.35029318 kilograms per liter.
Real-world example
1,000 st/L × 6.35029318 = 6,350.29318 kg/L
1,000 stones per liter = 6,350.29318 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 liter?
1 stone per liter equals 6.35029318 kilograms per liter, using the exact defined conversion factor rather than an estimate.
How do I convert stone per liter to kilogram per liter?
Multiply the stone per liter value by 6.35029318. The converter above does this instantly to whatever precision you set.
How do I convert kilogram per liter back to stone per liter?
Use the reverse factor: 1 kilogram per liter equals 0.1574730444 stones per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a stone per liter?
Stone per Liter (st/L) 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 liter to kilogram per liter conversion exact?
Yes. Both stone per liter and kilogram per liter 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.
