About these units

Metric Ton (t)

Metric (SI)Current unit

1,000 kilograms (about 2,204.6 lb), also spelled tonne. Used for cargo, grain and vehicle weights outside the US.

Barrels gave the tonne its name. The word goes back to a Germanic root for a large cask, the tun, and a full tun could easily weigh around a tonne. In English this became ton; the spelling tonne has been used in France since 1842, where it replaced the older tonneau, and pre-metric French tonnes were 2,000 livres, about 979 kg. Once the metric system took hold, the tonne was fixed at 1,000 kilograms, which is the mass of roughly a cubic metre of water.

The unit is accepted for use with the SI, and its symbol is a lowercase t with no period. Because it sits close to the old English ton, the two get confused: the short ton used in the US is about 10 percent lighter than a tonne, while the long ton differs by less than 2 percent. NIST calls the unit the metric ton, and the spelling tonne is rare in the US. Very large quantities are stated in prefixed forms such as the megatonne, which equals a teragram. In explosives, a tonne of TNT is taken as about 4.2 gigajoules.

1 metric ton = 1,000 kilograms (exactly).

Arroba (Brazilian) (@)

Spanish & PortugueseTraditional unit (still used in some regions)

Exactly 15 kg. Used in Brazil for the weight of cattle and cotton.

Arabic ar-rubʿ, a quarter, is the root of arroba, which was a fourth of a quintal in the Iberian trade world. Portugal carried the unit to Brazil, and in Portugal the arroba was about 14.7 kilograms, while parts of Spain such as Galicia, Aragon and Andalusia used about 11.5.

Brazil's modern metric arroba is 15 kilograms, the figure used here, and the agricultural sector still relies on it, mainly for cattle and cotton. Elsewhere in Latin America the value differs: 12.5 kilograms in Colombia, Ecuador and Peru, while Bolivia's national arroba is a volume of 30.46 liters. Because the symbol @ is also the word arroba in Spanish and Portuguese, the same sign serves as the email at-sign in those languages.

1 arroba (Brazilian) = 15 kilograms (exactly).
