About these units

Catty (Hong Kong) (catty)

ChineseTraditional unit (still used in some regions)

Exactly 1⅓ pounds (about 604.79 g). The legal Hong Kong catty, used in markets.

Kati, the Malay word behind catty, reached English through traders along the South China coast, and the Hong Kong version is the one most travellers meet in wet markets today. In 1884 Hong Kong law tied the catty to British weights as exactly one and one third avoirdupois pounds. With the pound taken as 0.45359265 kg, that gives 604.78982 g, the figure used here, which is a little over 600 g.

The Hong Kong catty is 16 taels and 100 of them make a picul of about 60.48 kg. That makes it heavier than the 500 g jin of mainland China, where the market system was redefined in 1930 and again in 1959 to ten liang per jin. Chinese weights themselves have wandered, from about 250 g in the Pre-Qin period to about 590 g under the Ming and Qing, with 16 liang per jin throughout. Vegetables, meat and herbs in Hong Kong are still often sold by the catty, and shops in Malaysia and Singapore use almost the same value, 604.79 g and 604.8 g respectively.

1 catty (Hong Kong) = 0.6047898267 kilograms (approximately).

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).
