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 Mina (mina)

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

About 436.6 g, equal to 100 drachmas. A mina of silver was a considerable sum in ancient Athens.

Mina is a borrowed word. It traces back to a Semitic root meaning to count, appearing as manu in Akkadian and maneh in Hebrew, and Greek mna was taken from the same source. In Babylonia the mina was a standard of silver weight by about 2000 BCE, at roughly 570 grams. The Greeks adopted both the word and the sixty-to-one link between mina and talent, but fitted the unit to their own coinage.

The Attic mina of Athens is usually given as about 436.6 grams, the figure used here, though other estimates run a few grams lower, near 431 grams. Cities such as Aegina used a heavier mina of about 624 grams, so a sum in minas meant little without knowing the standard. According to the sources, the mina first counted 70 drachmas and was raised to 100 around the time of Solon, about 594 BC. That decimal relation made it handy for bookkeeping, with 100 drachmas to the mina and 60 minas to the talent. A modern comparison is a little under a pound, about 0.96 pound avoirdupois.

1 Attic mina = 0.4366 kilograms (approximately).
