About Converting Carats per Pint to Stones per Liter
Carat per Pint and Stone 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
stones per liter = carats per pint × 0.0000665599637359
This factor comes from each unit's defined relationship to the category's base unit: 1 carat per pint equals 0.422675283773 base units, and 1 stone per liter equals 6350.29318 base units, so dividing one by the other gives the direct carat per pint-to-stone per liter factor of 0.0000665599637359.
Simple example
1 ct/pt × 0.00006655996374 = 0.00006656 st/L
1 carat per pint = 0.00006656 stones per liter.
Real-world example
1,000 ct/pt × 0.00006655996374 = 0.0665599637 st/L
1,000 carats per pint = 0.0665599637 stones per liter.

Frequently asked questions
How many stones per liter are in 1 carat per pint?
1 carat per pint equals 0.00006656 stones per liter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per pint to stone per liter?
Multiply the carat per pint value by 0.00006655996374. The converter above does this instantly to whatever precision you set.
How do I convert stone per liter back to carat per pint?
Use the reverse factor: 1 stone per liter equals 15,024.04665 carats per pint. You can also use the swap control in the converter above to flip the direction instantly.
What is a carat per pint?
Carat per Pint (ct/pt) is a unit of density.
What is a stone per liter?
Stone per Liter (st/L) is a unit of density.
Is the carat per pint to stone per liter conversion exact?
Yes. Both carat per pint and stone per liter are defined by fixed standards rather than physical artifacts, so the factor of 0.00006655996374 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.
