Common weight units

Carat (ct)

Definition: A carat (symbol: ct) is a unit of mass equal to exactly 200 milligrams, or 0.2 grams. It is primarily used for gemstones and pearls.

History/origin: The carat originated from the carob seed, which was historically used as a rough standard for weighing gemstones because of its relatively uniform size. The metric carat was standardized in the early 20th century.

Current use: Carats are used almost exclusively in jewellery and gem trading to describe the weight of diamonds and other precious stones.

Metric ton (t)

Definition: The metric ton, or tonne, is a large metric mass unit. One t equals 1,000 kg, or one million grams.

History/origin: Metric trade needed a unit larger than the kilogram for bulk goods, and the tonne provided a decimal-friendly measure for heavy loads.

Current use: T is common in freight, grain markets, steel production, carbon emissions, vehicle weights, mining output, livestock feed, and international shipping.
