About Metric Tons
A metric ton (t), also called a tonne, equals exactly 1,000 kilograms. It is the standard large mass unit in the international SI system, used worldwide for shipping, trade, agriculture, industry, and environmental monitoring. Global steel production, grain harvests, CO₂ emissions, shipping freight, and oil production are all reported in millions of metric tonnes. A standard TEU shipping container can carry up to approximately 28 metric tonnes of cargo. Carbon footprint calculators express emissions in CO₂ equivalent tonnes (tCO₂e).
About Carats
A metric carat (ct or CD) is exactly 200 milligrams (0.2 g), the universal standard for weighing gemstones. Established internationally in 1907, it replaced fractionally different regional carat weights previously used in different countries. The total weight of a diamond or colored gemstone is always expressed in carats: a 1.00 ct diamond of excellent cut and color can command over $5,000. The Cullinan diamond, the largest gem-quality rough diamond ever found, weighed 3,106.75 carats.
