About these units

Ounce (oz)

US & ImperialCurrent unit

One sixteenth of a pound, exactly 28.349523125 g. Used for food, mail and consumer goods in the US and UK.

A twelfth part is what ounce originally meant. It comes from the Roman uncia, one twelfth of the Roman pound, a word that also gave English the inch. The abbreviation oz does not come from English at all but from the Italian onza or oncia. Over the centuries many regions and trades used different ounces: the English Tower ounce of 29.16 g was abolished by Henry VIII in 1527, and the Dutch ons was redefined as exactly 100 g in 1820.

The avoirdupois ounce used for everyday goods is one sixteenth of a pound, exactly 28.349523125 g or 437.5 grains, the standard in the US and under the UK imperial system. It is not the same as the troy ounce for precious metals, and neither is the fluid ounce, which measures volume. Ounces still describe portions such as steaks and burgers, and they show up in unexpected places: fabric is graded by weight per area, so a 16 oz denim is a heavy cloth, and the copper on a circuit board is specified in ounces, where 1 oz is roughly 34.7 micrometres thick.

1 ounce = 0.02834952313 kilograms (approximately).

Qian (Chinese) (qian)

ChineseTraditional unit (still used in some regions)

Exactly 5 g in the modern Chinese market system; one tenth of a liang.

Sitting between the liang and the fen, the qian was the working unit for small quantities of silver, medicine and spice. Its character also named a coin, and the weight is closely tied to the old coinage. Traditional Chinese medicine prescriptions have long been written in qian, and a regulation from 1979 treated the medicinal qian as exactly 3 g so that doses could be converted cleanly to metric.

Its size depends on the jin that it divides. Under the Republic from 1930 the qian was 1/160 of a jin, which gives 3.125 g, and a 1915 law gave about 3.73 g. After the People's Republic redefined the liang as one tenth of a jin, the qian became one tenth of a liang, which is the figure used here: 5 g. Hong Kong and Macau use about 3.78 g, and Taiwan uses 3.75 g.

1 qian (Chinese) = 0.005 kilograms (exactly).
