About Converting Carats per Liter to Stones per Pint
Carat per Liter and Stone per Pint 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 pint = carats per liter × 0.00001490250795
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 pint equals 13420.5598595 base units, so dividing one by the other gives the direct carat per liter-to-stone per pint factor of 0.00001490250795.
Simple example
1 ct/L × 0.00001490250795 = 0.0000149025 st/pt
1 carat per liter = 0.0000149025 stones per pint.
Real-world example
1,000 ct/L × 0.00001490250795 = 0.014902508 st/pt
1,000 carats per liter = 0.014902508 stones per pint.

Frequently asked questions
How many stones per pint are in 1 carat per liter?
1 carat per liter equals 0.0000149025 stones per pint, using the exact defined conversion factor rather than an estimate.
How do I convert carat per liter to stone per pint?
Multiply the carat per liter value by 0.00001490250795. The converter above does this instantly to whatever precision you set.
How do I convert stone per pint back to carat per liter?
Use the reverse factor: 1 stone per pint equals 67,102.7993 carats per liter. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per liter?
Carat per Liter (ct/L) is a unit of density.
What is a stone per pint?
Stone per Pint (st/pt) is a unit of density.
Is the carat per liter to stone per pint conversion exact?
Yes. Both carat per liter and stone per pint are defined by fixed standards rather than physical artifacts, so the factor of 0.00001490250795 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.
