What are millimeters to cts?

Answer 1

Millimeters (mm) and carats (cts) are units of measurement used for different purposes. Millimeters measure length, commonly used for the dimensions of gemstones, while carats measure weight, specifically for precious stones and pearls, where one carat is equivalent to 200 milligrams. There isn’t a direct conversion between the two since they quantify different attributes; however, for gemstones, a larger millimeter size generally indicates a higher carat weight, depending on the gemstone's density.
