About these units
Carat (car, ct)
The carat, equal to 200 milligrams, is the standard unit for measuring gemstones and pearls. Its origins trace to the seeds of the carob tree, which were historically thought to have remarkably uniform mass, making them convenient reference weights for early traders. In the modern gem trade, carats measure both weight and (informally) influence perceived value—though size and quality factors such as clarity and color also play major roles. High-precision digital scales capable of reading to 0.001 carat are common in gemology. The carat's persistence shows how specialized units evolve to meet the needs of niche industries. Though small, its economic impact is enormous due to the value of gemstones.
Metric Ton (t)
The metric ton, or tonne, equals 1,000 kilograms and is used for measuring large masses such as vehicles, industrial shipments, agricultural yields, waste disposal, and construction materials. Its convenient decimal relationship with kilograms makes it easy to use in logistics, industry, and environmental studies. Many countries express carbon emissions in tonnes of CO₂, linking the unit directly to global sustainability efforts. The metric ton contrasts with the US short ton and UK long ton—its exact definition prevents ambiguity in international trade. Its adoption worldwide demonstrates the advantages of standardized mass units in a global economy.
