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).

Quintal (q)

Metric (SI)Traditional unit (still used in some regions)

100 kilograms. Still used for crop yields in India, France and parts of Europe and South America.

Romance languages gave this unit its name, from the idea of a hundred base units, while German and Russian forms such as Zentner and tsentner follow the same logic. Before metrication a quintal was a hundred of some local pound, so it ranged widely: about 48.95 kilograms in France, around 46 in Spain, about 58.75 in Portugal and 50 in Germany.

The metric quintal fixed the figure at 100 kilograms, the value used here. Farmers in France, Italy, Poland, India and Indonesia still quote yields and prices in it, and wholesale grain in Ethiopia and Eritrea is priced per quintal, as it is in Brazil and some other South American countries. The United States wrote it into law in 1866 as 100 kilograms, though neither the US nor NIST uses it now. English-speaking trade once used the word as another name for the hundredweight, and in Newfoundland a 112 pound quintal was the salt-cod unit into the 1960s.

1 quintal = 100 kilograms (exactly).
