About Converting Stones per Liter to Carats per Liter
Stone per Liter and Carat 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
carats per liter = stones per liter × 31751.4659
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 carat per liter equals 0.2 base units, so dividing one by the other gives the direct stone per liter-to-carat per liter factor of 31751.4659.
Simple example
1 st/L × 31751.4659 = 31,751.4659 ct/L
1 stone per liter = 31,751.4659 carats per liter.
Real-world example
1,000 st/L × 31751.4659 = 31,751,465.9 ct/L
1,000 stones per liter = 31,751,465.9 carats per liter.

Frequently asked questions
How many carats per liter are in 1 stone per liter?
1 stone per liter equals 31,751.4659 carats per liter, using the exact defined conversion factor rather than an estimate.
How do I convert stone per liter to carat per liter?
Multiply the stone per liter value by 31751.4659. The converter above does this instantly to whatever precision you set.
How do I convert carat per liter back to stone per liter?
Use the reverse factor: 1 carat per liter equals 0.0000314946 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 carat per liter?
Carat per Liter (ct/L) is a unit of density.
Is the stone per liter to carat per liter conversion exact?
Yes. Both stone per liter and carat per liter are defined by fixed standards rather than physical artifacts, so the factor of 31751.4659 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.
