Carats Converter

Carat

A carat (ct) is a specialized metric unit used to measure gemstones and pearls. One carat equals 200 milligrams — or 0.2 grams — making it perfectly sized for tiny but valuable items. Jewelers and gemologists rely on carats because small weight differences can significantly affect a stone’s price and quality.

Carats provide precision without using long decimal values in grams or milligrams. However, when converting gemstone weights to more common units, exact conversion factors are necessary — and this is where a converter becomes helpful.

Carats in Everyday Measurement

Carats are most familiar in jewelry shopping, especially when choosing engagement rings or other fine gems. Product listings often include weight in carats to indicate size, along with cut, clarity, and color.

To understand a carat value in everyday terms, converting to grams or milligrams can give a clearer sense of the stone’s actual weight. This tool makes those conversions fast and accurate.
