Units explained
Dunam (Metric)
A metric dunam is a unit of land area equal to exactly 1000 m² (0.1 hectare or about 0.247 acre). Used widely in Israel, Turkey, and the Middle East.
Originally an Ottoman unit of variable size (see Ottoman dunam). The metric dunam was standardized at exactly 1000 m² in the 20th century for ease of conversion.
Metric dunams are the standard land measurement unit in Israel for both residential and agricultural property. Also widely used in Turkey, Cyprus, and other former Ottoman territories.
Standardized at 1000 m² in 20th century; Ottoman origin.
Arpent (French)
A French arpent is a historical unit of land area used in pre-metric France, approximately 4221 m² (close to one acre).
Originated as a medieval French land unit; varied considerably by province. The 'arpent de Paris' was officially fixed at 100 perches squared, the perche being 18 pieds.
French arpents appear in pre-revolutionary French land records and in genealogical research. The unit was largely abolished after the French Revolution in favor of metric units.
Medieval French origin; abolished after the French Revolution in favor of metric.
