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).

Kan (kan)

JapaneseTraditional unit (still used in some regions)

1,000 monme, exactly 3.75 kg. A traditional Japanese weight unit.

Long before it was a weight, the kan was a way to carry money: roughly a thousand copper coins strung together through their square holes. In China a bundle of this kind was recognised as a currency unit, and the mass unit came afterward, based on what a thousand such coins weighed.

Japan inherited both ideas. The kan equals 1,000 monme, and Edo-period measures averaged about 3.736 kg, drifting a little above 3.75 kg in the late Edo period. The Weights and Measures Act of 1891 ended the variation by defining the kan as 15/4 kg, exactly 3.75 kg, about 8.27 pounds. That is the figure used here.

The 1891 act made the shaku and the kan the foundation of the national system. Metric became the legal standard in 1924 and the sole one from 1959, leaving the kan as a non-statutory unit whose trade use is penalised, though shaved-ice blocks are still sold as kan-me.

1 kan = 3.75 kilograms (exactly).
