Convert Dunam to Hectare (dunam → ha)

Converting dunams to hectares is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in dunams

   Start with the number of dunams (dunam) you want to convert.
2. 2
   Multiply by 0.1

   The conversion factor from dunam to ha is 0.1. Multiply your value by this number.
3. 3
   Read the result in hectares

   The result is your value in hectares (ha).

Multiply the value in dunams by 0.1. For the reverse direction, multiply by 10.

• ✓1 dunam = 1000 m² = 0.1 ha.
• ✓10 dunams = 1 hectare.
• ✓Historical Ottoman dunam was 919.3 m² — avoid if possible; modern is 1000.

• ✗Using Ottoman dunam figures in modern Turkish contracts — assume metric.
• ✗Confusing with other Middle Eastern units (feddan, etc.).
• ✗Assuming all regional dunams are identical — confirm modern 1000 m² value.

What is the Dunam?

The dunam equals exactly 1,000 square meters in its modern metric form, used primarily in Israel, Jordan, Lebanon, Palestine, Syria, and Turkey for land measurement and real estate. The unit's name derives from Ottoman Turkish 'dönüm,' itself from a verb meaning 'to turn' — historically the area a yoke of oxen could plow in a day, similar to the acre's origin. Older 'Ottoman dunam' values varied (around 919 m²), but most countries in the region have standardized to the metric dunam of 1,000 m². The dunam is the everyday unit in Middle Eastern real estate and agricultural contexts. It relates to the square meter (1 dunam = 1,000 m² = 0.1 ha), the hectare (10 dunams = 1 ha), and the acre (1 acre ≈ 4.047 dunams). Family olive groves, vineyards, and urban building plots are routinely measured in dunams.

• Turkish rural property
• Agricultural documents in the former Ottoman region

What is the Hectare?

The hectare equals exactly 10,000 square meters (100 m × 100 m) and is the international standard area unit for agricultural land, forestry, and large land development. Adopted as part of the metric system in 1795, the hectare's name combines 'hect-' (one hundred) with 'are' (the basic metric land unit of 100 m²) — meaning 100 ares. A standard FIFA football pitch covers about 0.7 hectares, and Central Park in New York is approximately 341 hectares. Farms across Europe, Latin America, Africa, and Asia are sized in hectares (a small family farm might be 5–20 ha). The hectare relates to the square meter (1 ha = 10,000 m²), the square kilometer (100 ha = 1 km²), the acre (1 ha ≈ 2.471 acres), and the square mile (1 ha ≈ 0.00386 mi²). It is one of the few non-SI units accepted for use with SI for legal land measurement.

• Forestry and conservation land
• Large construction projects and urban development
