About these units
Square Kilometer (km²)
One million square meters (100 hectares). Used for the area of cities, countries and lakes.
Metric land measure took a surprisingly long time to settle on the kilometer. The meter was defined in 1799, yet people initially preferred the myriameter, 10,000 meters, and the French phrase myriamètres par heure was still in print in 1802. The Netherlands adopted the kilometer in 1817 under the name mijl. Once the kilometer was established, the square kilometer followed naturally as the unit for areas too large to count comfortably in hectares or square meters.
One square kilometer is 1,000,000 square meters, or 100 hectares, about 0.3861 square miles or 247.1 acres. A useful picture comes from history: many medieval European cities were enclosed by walls around roughly a square kilometer, with Delft at about 0.9 km² and Lucca at about 1.09 km². A standard 18-hole golf course of 6,000 meters needs about 0.8 km². The symbol km² means the square of a kilometer, not a thousand square meters. The planned Square Kilometre Array radio telescope takes its name from the collecting area it aims for.
1 square kilometer = 1,000,000 square meters (exactly).

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).
