Faddan

A feddan (Arabic: فدّان‎‎, faddān) is a unit of area. It is used in Egypt, Sudan, Syria and the Sultanate of Oman. In Classical Arabic, the word means 'a yoke of oxen': implying the area of ground that could be tilled by them in a certain time. In Egypt the feddan is the only non-metric unit which remained in use following the switch to the metric system. A feddan is divided into 24 kirat (Arabic: قيراط, qīrāt) which equals 175 square meters.

1 feddan = 24 kirat = 60 metre × 70 metre = 4200 square metres (m²) = 0.42 hectares = 1.038 acres

In Syria, the feddan ranges from 2295 square metres (m²) to 3443 square metres (m²).
