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).

Dan (Chinese) (dan)

ChineseTraditional unit (still used in some regions)

100 jin, or 50 kg in the modern market system. Historically known as the picul; Hong Kong's picul is about 60.48 kg.

Dan means a burden, and the character 擔 shows a person carrying a load on a pole across the shoulders. The same unit is written 石 in older texts and is known in English as the picul, a word borrowed from Malay for carrying something on the shoulder. For most of imperial history a dan was 120 catties, roughly what one porter could manage, and it served for rice, salt, tea and other bulk goods moved by caravan, boat or road.

Because the underlying jin changed from dynasty to dynasty, the dan drifted too. The jin was about 250 g before the Qin, around 220 g under the Eastern Han, about 633 g in the Tang and Song periods, and about 590 g under the Ming and Qing. The Republic of China fixed the market system in 1930 and the People's Republic kept it, so the figure used here is 100 jin of 500 g, or exactly 50 kg. That is a convenient fifty-kilogram sack, and it still appears in farm and grain statistics. Hong Kong kept its own picul of 60.478982 kg.

1 dan (Chinese) = 50 kilograms (exactly).
