square kilometer → dunam | Converter
Convert square kilometer to dunam with the formula below. 1 km² ≈ 1,000 dunam
Quick Insight
1 square kilometer = 1,000 dunam
2.5 km² ≈ 2,500 dunam. Because the destination unit is smaller, the numeric result is larger for the same positive area.

Mathematical Facts
Convert square kilometer to dunam with the formula below. dunam ≈ km² × 1,000. 1 km² ≈ 1,000,000 m²; 1 dunam ≈ 1,000 m² For km² → dunam, keep the original surface unchanged and change only its unit. Square kilometers keep a mapped region’s area readable without a long total in square meters. A square measuring 1 km on each side covers 1,000,000 m², not 1,000 m². This calculator defines one dunam as 1,000 m². Use it for a field-area record only when that record uses the same metric convention; the name alone does not establish its definition.
Why This Conversion Matters
A field list and a map summary may use different land-area units. Convert their areas before adding or comparing them, and keep the same included boundaries; a new unit does not change what was measured. Because the destination unit is smaller, the numeric result is larger for the same positive area. The calculator uses the full stored factor and rounds displayed results to 12 significant digits. Display precision is not a guarantee of measurement accuracy.
Real-World Examples
Land and habitat summaries
These hypothetical rectangles illustrate how a known area changes units for comparison with a land summary. The second total combines two separate, equal areas. Actual irregular regions require a measured area rather than an assumed rectangle.
Examples:
- Rectangular map region: 5 km × 0.5 km = 2.5 km² ≈ 2,500 dunam
- Two equal, non-overlapping areas: 5 km² ≈ 5,000 dunam
Pro Tips:
- ✓Combine only non-overlapping areas, and retain the same boundary definition in both units.
Quick Reference Table
| square kilometers | dunams |
|---|---|
| 1 km² | 1,000 dunam |
| 2 km² | 2,000 dunam |
| 5 km² | 5,000 dunam |
| 10 km² | 10,000 dunam |
| 20 km² | 20,000 dunam |
Formula: dunam = km² × conversion factor
Common Mistakes to Avoid
Assuming the name dunam always means the calculator’s unit
A record using a different definition will not describe the same area when its number is entered here. This calculator consistently uses 1 dunam = 1,000 m².
✓ Label the destination as metric dunam, 1,000 m² per dunam, so the result retains its meaning.
Pro Tips
- ✓Keep km² separate from km: a route length cannot be converted into an area without additional dimensions.
- ✓Check that the source defines its dunam as 1,000 m² before using this result for a comparison.
- ✓Combine only non-overlapping areas, and retain the same boundary definition in both units.
Frequently Asked Questions
How do I calculate the conversion?
dunam ≈ km² × 1,000. 1 km² ≈ 1,000,000 m²; 1 dunam ≈ 1,000 m²
What is an example?
1 km² ≈ 1,000 dunam; 10 km² ≈ 10,000 dunam; 100 km² ≈ 100,000 dunam
What should I check specifically for km² → dunam?
A record using a different definition will not describe the same area when its number is entered here. This calculator consistently uses 1 dunam = 1,000 m². Label the destination as metric dunam, 1,000 m² per dunam, so the result retains its meaning. 2.5 km² ≈ 2,500 dunam.
Can this area result determine a perimeter?
No. An area value does not uniquely determine the shape or perimeter. Keep a map or the measured boundary lengths if those are needed; the converter only changes the unit of an existing area.
