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).

Attic Drachma (drachma)

Ancient GreekHistorical unit (no longer in standard use)Approximate value

About 4.366 g of silver. The weight of the basic ancient Greek coin of the same name.

Greek drassomai means to grasp, and the drachma is usually explained as a handful. Early bullion money took the form of metal rods, and six of them made a fistful. When coins replaced the rods, the name stayed with the coin that stood for that handful. Cities minted drachmas to different weight standards, and the Athenian or Attic one became the most widespread. It is commonly put at a little over 4.3 grams of silver, and the figure used here, 4.366 grams, is one estimate within that range.

Surviving coins and weights depart noticeably from any theoretical value, so the true standard remains somewhat uncertain. Six obols made one drachma, and 100 drachmas made a mina. In the fifth and fourth centuries BC a skilled worker or soldier earned roughly one drachma a day. Athenian silver from the Laurion mines had a reputation for purity. A drachma weighs about as much as a modern teaspoon of sugar, roughly a seventh of an ounce, and its name was revived for Greece's national currency from 1833 until the euro arrived in 2002.

1 Attic drachma = 0.004366 kilograms (approximately).
