How do I convert carats to stones using LetsConvert?

Enter the carat value in the input field, choose 'Carat' as the source unit and 'Stone' as the target, then hit Convert. The tool applies the exact conversion factor: 1 carat = 0.000031494 stones (1 carat = 0.2 g, 1 stone = 6,350.29318 g). You can copy the result directly or adjust decimal precision in settings.

Why would I need to convert carats to stones?

Carats measure gemstone mass (0.2 g each), while stones are an imperial unit for body mass (14 lbs). Converting between them is useful for international jewelry trade, bulk gemstone estimations in Commonwealth countries, or comparing a gem's weight to human body weight. It also helps in historical documents where gemstone weights were recorded in stone units.

How does the converter handle decimal precision and rounding for carat-to-stone results?

The converter uses arbitrary-precision arithmetic based on the official definitions: 1 carat = 0.2 g and 1 stone = 6,350.29318 g. This eliminates floating-point errors. By default, results show 10 decimal places, but you can increase this up to 15. The output preserves the input's significant digits; for example, 1.234 carats converts to 0.000038873 stones without truncation.
