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).

Acre (ac)
43,560 square feet or exactly 4,046.8564224 m², about 40% of a hectare. Originally the area a yoke of oxen could plow in a day.
Ploughland gave the acre its name: it traces to Old Norse akr, meaning cultivated land, and is related to German Acker and Latin ager. In medieval England it was a farming measure, the land one man with a team of eight oxen could plough in a day. The traditional strip was 40 perches long and 4 perches wide, which is 660 by 66 feet, or ten square chains. The shape was never the point, and the article on the unit stresses that any area of 43,560 square feet is an acre.
An acre is 43,560 square feet, 4,840 square yards or 1/640 of a square mile, close to 0.4 hectare. For Americans, it is roughly 88 by 55 yards, about 90 percent of a football field without the end zones. The Weights and Measures Act 1878 fixed it at 4,840 square yards in Britain, where trade use ended in 1995. The 1959 international acre is exactly 4,046.8564224 m²; the US survey acre, about 4,046.872 m², differed slightly, and US survey units were retired after 2022.
1 acre = 4,046.856422 square meters (approximately).
