The Simplest Conversion in Land Measurement
Of all the conversions involving the dunam, the relationship to square meters is the most straightforward: the modern metric dunam is defined as exactly 1,000 square meters. This makes dunam-to-square-meter conversion as simple as multiplying or dividing by 1,000.
Conversions to hectares are equally clean: since 1 hectare = 10,000 sq meters, one dunam equals exactly 0.1 hectares, meaning 10 dunams = 1 hectare.
The Core Equivalencies
- 1 dunam = 1,000 square meters
- 1 dunam = 0.1 hectares
- 10 dunams = 1 hectare
- 1 hectare = 10 dunams
- 1 square meter = 0.001 dunams

How to Convert: Step-by-Step
Converting Dunams to Square Meters
- Take your dunam value
- Multiply by 1,000
- Result is in square meters
Example: 7.5 dunams × 1,000 = 7,500 square meters
Converting Square Meters to Dunams
- Take your square meter value
- Divide by 1,000
- Result is in dunams
Example: 3,750 sq meters ÷ 1,000 = 3.75 dunams
Converting Dunams to Hectares
- Take your dunam value
- Divide by 10
- Result is in hectares
Example: 35 dunams ÷ 10 = 3.5 hectares

When Conversions Get Complicated: The Old Dunam
The tables above assume the modern metric dunam of 1,000 sq meters. If you're working with older documents — particularly pre-1928 records from British Mandatory Palestine, or pre-20th-century Ottoman registrations — the dunam may have been recorded as approximately 919–940 sq meters. In this case, you'll need to apply the historically appropriate value for accurate conversion.
When in doubt: always confirm the applicable standard with a local land registry professional or lawyer.
