About these units
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).

Square Meter (m²)
The SI unit of area: a square one meter on each side. Used for floor areas and property sizes in most of the world.
Squaring the meter was built into the metric system from the start. The French law of 18 Germinal, Year III (7 April 1795) defined the are, the land unit that gave the hectare its name, as exactly 100 square meters, so the square meter was already the foundation of metric land measure. Nobody is credited with inventing it as a separate unit. It is simply the area of a square one meter on each side, and any SI prefix that works for the meter works for it, with the prefix squared along with the unit.
That squaring catches people out: a square kilometer is one million square meters, not one thousand. Since 1983 the meter has been defined through the speed of light, so the square meter is tied to a constant of nature as well as to the second. A hectare, about the area of Trafalgar Square in London, is 10,000 square meters. In everyday terms one square meter is about 10.76 square feet. Unicode has a compatibility character for it, but the recommended way to write it is the plain superscript two: m².
The square meter is the reference unit for area on this site.
