Convert Dunam to Square Kilometer (dunam → km²)

Converting dunams to square kilometers 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 0.001

   The conversion factor from dunam to km² is 0.001. Multiply your value by this number.
3. 3
   Read the result in square kilometers

   The result is your value in square kilometers (km²).

Multiply the value in dunams by 0.001. For the reverse direction, multiply by 1,000.

• ✓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.

What is the Square Kilometer?

The square kilometer equals 1,000,000 square meters (or 100 hectares) and is the international standard for measuring large areas: cities, national parks, lakes, watersheds, and country-level statistics. Population density is conventionally given in people per km² (e.g., Singapore has roughly 8,400 people/km², Mongolia has fewer than 2). The largest US national park, Wrangell-St. Elias in Alaska, covers about 53,000 km². France is 643,801 km², and the largest country, Russia, spans 17 million km². The square kilometer relates to the square meter (1 km² = 1,000,000 m²), the hectare (1 km² = 100 ha), the square mile (1 km² ≈ 0.386 mi²), and the acre (1 km² ≈ 247.1 acres). Geographic information systems, climate science, and regional planning all rely on square kilometers as the base unit for area.
