About these units

Jō (jō)

JapaneseTraditional unit (still used in some regions)

Ten shaku, exactly 100/33 meter (about 3.03 m).

Jo, written with the character for a tall person or elder, is the largest of the everyday shaku multiples, standing at ten shaku. Do not confuse it with the other jo, the counter for tatami mats, which describes floor area rather than length.

With the shaku fixed at 10/33 meter by Japan's 1891 law, one jo comes to exactly 100/33 meter, about 3.03 meters or 9.94 feet. Earlier values shifted with the shaku, which ranged from roughly 30.2 to 30.3 centimeters, so premodern figures in jo are good only to within a centimeter or two per shaku.

It sits between the ken, at six shaku, and the chō, at 360 shaku. Its use outside tradition is limited. Modern building plans and trade measures use meters, so the jo appears mainly in historical texts, descriptions of temples and in discussion of the older measuring system.

1 jō = 3.03030303 meters (approximately).

Mile (mi)

US & ImperialCurrent unit

5,280 feet or 1,760 yards, exactly 1,609.344 meters. This is the statute (international) mile used on US and UK roads.

A thousand paces gave the mile its name. It descends from the Latin mille passus, the Roman mile, by way of Old English mil and Middle English myle. For centuries after Rome, miles of many lengths coexisted; a sixteenth-century Mercator map, for example, shows small, medium and large Flemish miles on a single scale bar. The English statute mile was fixed by an Act of Parliament under Elizabeth I in 1593, which declared that a mile contains eight furlongs, or 5,280 feet.

The 1959 international yard and pound agreement made that mile exactly 1,609.344 meters. A slightly longer US survey mile, about 1,609.347 meters, lingered in American land surveys and was slated for retirement from 1 January 2023. Today the mile is the road unit of the United Kingdom, the United States, Liberia and Myanmar, along with several territories such as the Bahamas, Belize, Guam and the US Virgin Islands. In Canada it survives chiefly in rail transport and horse racing.

1 mile = 1,609.344 meters (exactly).
