Dunam

[edit | edit source]

Dunam (also spelled dunum; Turkish: dönüm) is a unit of area used in several countries and regions that were historically influenced by the Ottoman Empire. In modern metric usage in places such as Israel, Palestine, and Turkey, a dunam is commonly defined as exactly 1,000 square metres (i.e., one decare), which is one‑tenth of a hectare.[1][2]

Definition

[edit | edit source]

The metric dunam is:

  • 1 dunam = 1,000 m²
  • 10 dunams = 1 hectare (since 1 hectare = 10,000 m²)

In other words, the metric dunam corresponds to the decare (da).[1]

History

[edit | edit source]

Historically, the size of a dunam could vary by region and period within the Ottoman realm. Modern references describe a shift toward a standardized metric definition (1,000 m²) in many places where the term remains in use.[1][2][3]

Usage

[edit | edit source]

Dunam is commonly used to express:

  • agricultural plot areas
  • land registry / real estate plot sizes (depending on jurisdiction)
  • everyday land measurement in rural contexts
