About these units

Shaku (shaku)

JapaneseTraditional unit (still used in some regions)

The Japanese foot, defined as exactly 10/33 meter (about 30.3 cm). Still the basis of carpentry and building dimensions in Japan.

Shaku is the Japanese reading of the character for chi, the Chinese foot, which began as a hand span from thumb tip to fingertip. Japan adopted the Chinese measuring system around the year 701, and the shaku became its basic length, growing over the centuries to roughly a third of a meter.

Several versions coexisted. The ordinary carpenter's shaku, the kanejaku, was about 30.2 to 30.3 centimeters. A longer kujirajaku, used for cloth and said to have been marked on whale baleen, measured 125/330 meter, near 37.9 centimeters. A longer variant, the korai-shaku, was about 1.17 times the modern value, about 35.5 centimeters.

The Weights and Measures Act of 24 March 1891 ended the variation for the standard unit by defining it as exactly 10/33 meter, about 30.3 centimeters or 11.93 inches. Official use was banned in 1966, yet the shaku still sets building dimensions: a standard three shaku panel is rounded to 910 millimeters.

1 shaku = 0.303030303 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).
