Formula
To execute this calculation, the value in Carat is first normalized to the base Weight unit (Kilogram) before being scaled to Stone. The direct multiplier for Carat to Stone is determined by the ratio of their scientific definitions.
Examples
For instance, 1 ct is strictly defined as roughly 0.00003149462465493702 st. If you are dealing with a larger scale, such as 50 ct, the resulting st value maintains this exact linear proportionality.
Reverse Formula
The inverse conversion (Stone back to Carat) is equally valid and uses the reciprocal of the primary ratio. Our interface allows you to toggle this direction instantly to verify both sides of the Weight equation.
Common Mistakes
The most frequent error in ct to st calculations is the misapplication of unit prefixes (like centi- or milli-). Additionally, confusing Carat with similar units in different systems (like US vs. Imperial) can lead to significant discrepancies.
Accuracy Notes
At FastConverto, we use a 64-bit floating-point engine. For the Carat to Stone transition, this means your results are processed with enough precision to satisfy even rigorous laboratory requirements, though most users will find 2-4 decimal places sufficient for practical use.
Industry Use
This specific conversion is a staple in Weight-heavy industries. Whether it's Carat being used in raw material procurement or Stone being required for final product labeling, accurate data flow is essential for project interoperability.
