About these units
Mu (Chinese) (mu)
Exactly 10,000/15 m² (666.67 m²), one fifteenth of a hectare. The standard unit of farmland in China.
A mu was once a plot defined by a square count of bu, the double pace used as a surveying step. Han-era writers recalled that in earlier times 100 square bu made a mu, while in their own day 240 were needed, and calculations from Han rulers give a mu of roughly 461 m². The size kept shifting. The 1915 Beiyang government law defined it as 60 square zhang, about 614.4 m².
The Republic's 1930 market system settled on 1/15 of a hectare, which is the 666.67 m² used here, and the mu is the only traditional Chinese area unit that survived the 1959 State Council decree. Farmland statistics in China are still given in mu, so that 15 mu make one hectare and 1,500 mu a square kilometre. Hong Kong and Macau use a mou of about 761.4 m², while Taiwan and Japan use a unit of about 99.17 m². The idiom of one mu and three fen of land describes a person's small personal patch.
1 mu (Chinese) = 666.6666667 square meters (approximately).

Square Mile (mi²)
640 acres or about 2.59 km². Used for the area of cities, states and countries in the US and UK.
A thousand Roman paces, mille passus, became the mile, and under Elizabeth I Parliament fixed the statute mile at eight furlongs, or 5,280 feet, in place of the older Roman-based value. The square mile inherits that length. Its most famous use came in the United States: the Land Ordinance of 1785 started the Public Land Survey System so that western land could be surveyed and sold to pay war debts, beginning with the Seven Ranges in eastern Ohio.
In that system a section is roughly one square mile, or 640 acres, and a township is 36 sections in a square six miles on a side. One square mile is nearly 2.59 million square meters. Chicago's Midway International Airport, at about 650 acres, covers roughly 1.02 square miles. Beware the phrase mile square: a region 20 miles square has 400 square miles, but so does a rectangle 10 by 40 miles. The US survey version of the mile was retired from 1 January 2023, but the international square mile remains the unit for cities, states and countries in the US and UK.
1 square mile = 2,589,988.11 square meters (approximately).
