About Converting Carats per Pint to Stones per Cubic Meter
Carat per Pint and Stone per Cubic Meter 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 cubic meter = carats per pint × 0.0665599637359
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 cubic meter equals 6.35029318 base units, so dividing one by the other gives the direct carat per pint-to-stone per cubic meter factor of 0.0665599637359.
Simple example
1 ct/pt × 0.06655996374 = 0.0665599637 st/m3
1 carat per pint = 0.0665599637 stones per cubic meter.
Real-world example
1,000 ct/pt × 0.06655996374 = 66.55996374 st/m3
1,000 carats per pint = 66.55996374 stones per cubic meter.

Frequently asked questions
How many stones per cubic meter are in 1 carat per pint?
1 carat per pint equals 0.0665599637 stones per cubic meter, using the exact defined conversion factor rather than an estimate.
How do I convert carat per pint to stone per cubic meter?
Multiply the carat per pint value by 0.06655996374. The converter above does this instantly to whatever precision you set.
How do I convert stone per cubic meter back to carat per pint?
Use the reverse factor: 1 stone per cubic meter equals 15.02404665 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 cubic meter?
Stone per Cubic Meter (st/m3) is a unit of density.
Is the carat per pint to stone per cubic meter conversion exact?
Yes. Both carat per pint and stone per cubic meter are defined by fixed standards rather than physical artifacts, so the factor of 0.06655996374 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.
