Tips & common mistakes

Quick tips

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

Avoid these

  • 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.
