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).

Kin (kin)

JapaneseTraditional unit (still used in some regions)

160 monme, exactly 600 g. A traditional Japanese unit of weight, equal to 600 g.

Kin is the Japanese unit that older English sources call the catty. In Japan it was defined as 160 monme, or 16 hundredths of a kan.

After the 1891 Weights and Measures Act tied the kan to exactly 3.75 kg, the kin became exactly 600 g, which is the figure used here. That makes it about 1.32 pounds, a convenient size for everyday goods bought in modest quantities, and it is still the size commonly used for loaves of bread.

Japan moved to the metric system as the sole legal system from 1959, and trade use of the kin was prohibited. The older unit remains familiar to many Japanese shoppers as a size of 600 g.

1 kin = 0.6 kilograms (exactly).
