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.
