dunam
Areaexact by definition
The metric dunam is exactly 1,000 square metres, one tenth of a hectare. It is the everyday unit of land area in Israel, Jordan, Lebanon, Syria and Turkey, where the Turkish spelling is dönüm, and agricultural yields and real estate in those countries are quoted per dunam.
Watch out: Ottoman-era land records use the old dunam of roughly 919.3 m², about 8% smaller. Old title deeds and modern cadastral areas are therefore not directly comparable.

Where the unit came from
The Ottoman dunam was defined as forty standard paces square and ran near 920 m². When the successor states metricated they rounded it to a clean 1,000 m², which is the value in use today.
