About these units

Feddan (fd)

Middle EasternTraditional unit (still used in some regions)Approximate value

About 4,200 m² (1.037 acres). The standard unit of farmland in Egypt, divided into 24 qirat.

In Classical Arabic faddan meant a yoke of oxen, so the name points to the ground a team could plough in a season. That idea explains why the feddan was never a single fixed size everywhere: in Syria it stayed vague, covering roughly 5 to 12 hectares of land worked by a pair of oxen over a year.

Egypt gave it a precise value. The metric system became optional there in 1873 and compulsory for government use in 1891, and the 1891 equivalences set the feddan near 4,200.8 square metres. The main Wikipedia article rounds this to 4,200 square metres, based on a plot of 60 by 70 metres, and the figure used here follows that article. The two readings differ by well under a tenth of a percent, or about 1.04 acres.

The feddan is divided into 24 qirat, each about 175 square metres, with a finer sahm equal to one 576th of a feddan. It was the one non-metric unit that stayed in everyday use in Egypt after metrication, and it is still the normal measure for farmland there, with use in Sudan, South Sudan and Oman as well.

1 feddan = 4,200 square meters (approximately).

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).
