About these units
Cun (Chinese) (cun)
The Chinese inch, 1/30 m (about 3.33 cm) in the modern market system. Also used in acupuncture, where a 'body cun' is proportional to the patient.
Hand anatomy gave the cun its role. The traditional definition is the width of a person's thumb at the knuckle, and the unit is commonly translated as the Chinese inch. That human scale is the reason acupuncture still uses a body cun, which is proportional to the patient and is not a fixed number of millimeters. Two forefingers side by side are counted as 1.5 cun, and four fingers together as 3 cun.
As a measure of ordinary objects, the cun is one tenth of a chi and ten times a fen. Under the modern market system it equals 10/3 centimeters, roughly 3.33 cm. Hong Kong kept a British-influenced standard in which the cun is about 3.715 cm, and Japan's related sun is about 3.03 cm, so the same character covers several different sizes in different places. The phrase chi cun, literally foot and inch, also became the everyday Chinese word for dimensions.
1 cun (Chinese) = 0.03333333333 meters (approximately).

Mile (mi)
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).
