Dönüm, Square Meters and Hectares
Land areas in Turkey are commonly expressed in dönüm. The modern (metric) dönüm is exactly 1,000 m²; that means 1 dönüm = 0.1 hectares and 1 hectare = 10 dönüm. Besides the dönüm, this tool converts square meters, square kilometers, hectares, acres, square feet and square yards — all at once.

Frequently Asked Questions
How many square meters is 1 dönüm?
The modern (metric) dönüm used in Turkey today is exactly 1,000 square meters. So 1 dönüm = 1,000 m² = 0.1 hectares. A 5-dönüm parcel is 5,000 m².
What is the difference between the old and new dönüm?
The historical (Ottoman) dönüm was about 918.672 m² (1,600 square arşın). With metrication, the dönüm was redefined as exactly 1,000 m². This tool uses the modern dönüm (1,000 m²), the official and common value in Turkey today — keep the difference in mind when working with old land records.
How many dönüm is 1 hectare?
Since 1 hectare = 10,000 m², one hectare is exactly 10 dönüm. Conversely, 1 dönüm is 0.1 hectares. Hectares and dönüm convert easily through this factor of 10.
