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.
Gram
A gram (g) is a metric unit equal to one-thousandth of a kilogram. It is ideal for measuring lighter items such as spices, medication, small hardware, and jewelry. Because it fits well for everyday small quantities, grams are widely used in cooking, product packaging, and laboratory work.
As part of the metric system, converting grams to kilograms or milligrams is quick and intuitive. But switching between grams and US customary units often requires exact conversion factors, where a converter becomes essential.
