The dunum across the Levant and Iraq
The dunum is an Ottoman-era unit that remained the land language of the Mashreq even as its value varied by region. Today it has settled on two main values: the metric dunum = 1,000 m² used in Jordan, Palestine, Lebanon, and Syria (so 10 dunums = 1 hectare), and the Iraqi dunum = 2,500 m² used in Iraqi land-registry records, dividing into 25 olk (1 olk = 100 m²).
Mixing the two upends any deal's arithmetic: a "10-dunum" parcel in Amman means 10,000 m², while in Baghdad it means 25,000 m² — a 2.5× difference. The historical Ottoman dunum carried several provincial values, which is why we leave it to historical context rather than model it as a unit. Always confirm which country the deed was issued in before converting.
For official transactions and inheritance splits, arithmetic alone is not enough — you need a certified survey and a stamped map. Request a scoped quote.
FAQ
- How many square metres is a dunum?
- The metric dunum is exactly 1,000 m² — the standard used today in Jordan, Palestine, Lebanon, and Syria. The Iraqi dunum is 2,500 m².
- How big is the Iraqi dunum, and what is an olk?
- The Iraqi cadastral dunum is 2,500 m² and divides into 25 olk, so one olk = 100 m² — the units used in Iraqi land-registry records.
- What is the dunum in Jordan, Palestine, Lebanon, and Syria?
- All four use the unified metric dunum: 1,000 m² (10 dunums = 1 hectare). The historical Ottoman dunum had varying regional values, which is why the tool does not model it as a unit.
- What is the difference between dunum, feddan, and hectare?
- A hectare = 10,000 m² = 10 metric dunums = 4 Iraqi dunums. The Egyptian feddan = 4,200.83 m² ≈ 4.2 metric dunums or 1.68 Iraqi dunums. The tool above converts between all of them instantly.
- Is the converter enough for a property transaction or inheritance split?
- The math is exact, but official transactions and disputes need a certified on-site survey and a stamped map by a licensed engineer — a service our team provides.
