About these units

Hectare (ha)

Metric (SI)Current unit

10,000 square meters (2.471 acres). The standard unit for land and agricultural areas outside the US.

Hecto plus are: the name was coined in French, and are itself comes from the Latin area, meaning an open space. The French law of 18 Germinal, Year III (7 April 1795) defined the are as 100 square meters, and the hectare followed as 100 ares, or 10,000 square meters. The unit is therefore a product of the original French metric reforms rather than of later SI work, which is one reason its official status has always been slightly awkward.

When the SI was set up in 1960 the are was not recognized, and the hectare was classed as a non-SI unit accepted for use with it. In practice it is the standard unit for land ownership, planning and agriculture in the European Union, the United Kingdom, Canada, Australia, New Zealand and South Africa, while the United States and Myanmar stay with the acre. A hectare is a square 100 meters on each side, about the size of Trafalgar Square, and equals roughly 2.47 acres. One hundred of them make a square kilometer.

1 hectare = 10,000 square meters (exactly).

Qing (Chinese) (qing)

ChineseTraditional unit (still used in some regions)

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).
