About these units
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).

Qing (Chinese) (qing)
100 mu: about 6.67 hectares (66,667 m²). A traditional Chinese land unit.
Where the mu suits a family plot, the qing counts large holdings. It is defined as 100 mu, which comes to 6.67 hectares in the modern market system, or about 16.47 acres. Wikipedia glosses it in English as the Chinese hide, borrowing an old English term for a household's farmland.
Its size depends entirely on the mu beneath it. With the 1915 mu of 614.4 m² a qing was about 6.1 hectares, and with the 1930 mu of 666.67 m² it is the figure used here. Older dynasty values were smaller still, as the Han mu worked out to only about 461 m². The qing is now mostly a historical and literary term, and Chinese agriculture reports land in mu, hectares or, for large areas, in ten thousands of mu.
1 qing (Chinese) = 66,666.66667 square meters (approximately).
