About Converting Carats per Liter to Stones per Teaspoon
Carat per Liter and Stone per Teaspoon 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
stones per teaspoon = carats per liter × 1.552345e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per liter equals 0.2 base units, and 1 stone per teaspoon equals 1288373.74651 base units, so dividing one by the other gives the direct carat per liter-to-stone per teaspoon factor of 1.552345e-7.
Simple example
1 ct/L × 1.552345e-7 = 1.552345e-7 st/tsp
1 carat per liter = 1.552345e-7 stones per teaspoon.
Real-world example
1,000 ct/L × 1.552345e-7 = 0.0001552345 st/tsp
1,000 carats per liter = 0.0001552345 stones per teaspoon.

Frequently asked questions
How many stones per teaspoon are in 1 carat per liter?
1 carat per liter equals 1.552345e-7 stones per teaspoon, using the exact defined conversion factor rather than an estimate.
How do I convert carat per liter to stone per teaspoon?
Multiply the carat per liter value by 1.552345e-7. The converter above does this instantly to whatever precision you set.
How do I convert stone per teaspoon back to carat per liter?

What is a carat per liter?
Carat per Liter (ct/L) is a unit of density.
What is a stone per teaspoon?
Stone per Teaspoon (st/tsp) is a unit of density.
Is the carat per liter to stone per teaspoon conversion exact?
Yes. Both carat per liter and stone per teaspoon are defined by fixed standards rather than physical artifacts, so the factor of 1.552345e-7 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.
