About these units

Sun (sun)

JapaneseTraditional unit (still used in some regions)

One tenth of a shaku, about 3.03 cm. The Japanese 'inch', still used in carpentry.

Sun is the Japanese reading of the Chinese character for cun, the Chinese inch, which was traditionally the width of a person's thumb at the knuckle. Japan took the whole system over from China, and the sun kept its place as one tenth of the foot-like shaku.

Because the shaku was fixed in 1891 at 10/33 meter, the sun works out to 1/33 meter, about 30.3 millimeters or 1.19 inches. That makes it about 19 percent longer than a modern inch. Before the legal definition, the size drifted slightly between eras and regions, so older measurements in sun carry some uncertainty.

Smaller steps below it, such as the bu, divide it further. Today the sun survives mainly in carpentry, joinery and traditional crafts, where dimensions are still quoted in shaku and sun before being translated into the millimeters on modern rulers.

1 sun = 0.0303030303 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).
