About these units
Chō (chō)
60 ken, about 109.09 m. A traditional measure of distance along roads and the length of a block.
Cho is written with a character that also means town or block, and the unit appears under the same name for area, which Japanese Wikipedia notes alongside the length meaning. As a length it equals 60 ken, or 360 shaku, putting it between the ken and the ri.
Under the 1891 law it is exactly 1200/11 meter, about 109.09 meters or 358 feet. Because the ken was longer in the 16th century than after the Tokugawa reduction around 1650, a cho measured in an older document may have been several percent longer, so such figures should be treated as approximate.
Thirty-six cho make one ri, so the cho worked as a convenient step for road distances and field layouts. Today it is a historical and place-name unit: the modern metric replacement is simply about 109 meters, roughly one city block.
1 chō = 109.0909091 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).
