Ottoman dunams appear in pre-20th-century land records across the former Ottoman Empire. Modern usage has shifted to metric dunams (exactly 1000 m²).
Traditional Ottoman unit; largely superseded by metric dunam.

Originated as a Spanish colonial unit. Standardized at exactly 10,000 square varas (Spanish varas of about 0.836 m each).
Manzanas are still widely used in agricultural records and rural property in Nicaragua, Honduras, Costa Rica, Guatemala, and some other Central American countries. Used alongside hectares in modern legal documents.
