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).

Gram (g)

Metric (SI)Current unit

One thousandth of a kilogram. The standard unit for food quantities and small objects.

A gram was once defined as a small drop of the natural world. The French National Convention of 1795 set it as the absolute weight of a volume of pure water equal to a cube one hundredth of a metre on each side, a cubic centimetre. The reference temperature was first the melting point of ice and was later changed to the temperature of maximum density of water, about 4 degrees Celsius. The word came into French as gramme, from Late Latin gramma, itself from the Greek for a letter or small mark; in Late Antiquity it meant about one twenty-fourth of an ounce.

The gram was the base unit of mass in the centimetre-gram-second system, but in 1960 the SI took the kilogram as its base unit, which made the gram one thousandth of it. That is why it appears in so many everyday places: it is the standard for non-liquid ingredients in cooking and shopping, and nutrition labels commonly list contents per 100 g. For a sense of scale, a small paper clip or a pen cap weighs about a gram, and a Japanese 1-yen coin is close to exactly that, while a US penny is around 2.5 g.

1 gram = 0.001 kilograms (exactly).
