To convert square decimeters to hectares, multiply the value by 1 × 10⁻⁶. To go the other way, multiply hectares by 1,000,000 to get square decimeters.
| Square Decimeters (dm²) | Hectares (ha) |
|---|---|
| 1 dm² | 1 × 10⁻⁶ ha |
| 2 dm² | 2 × 10⁻⁶ ha |
| 5 dm² | 5 × 10⁻⁶ ha |
| 10 dm² | 1 × 10⁻⁵ ha |
| 20 dm² | 2 × 10⁻⁵ ha |
| 50 dm² | 5 × 10⁻⁵ ha |
| 100 dm² | 0.0001 ha |
| 500 dm² | 0.0005 ha |
| 1,000 dm² | 0.001 ha |
Square decimeter (dm²). A square decimeter is 100 square centimeters (0.01 m²).
Hectare (ha). A hectare is 10,000 square meters (100 m × 100 m), the world's standard unit for farmland and large plots.
There are 1 × 10⁻⁶ hectares in one square decimeter.
Multiply the number of square decimeters by 1 × 10⁻⁶. For example, 10 square decimeters equal 1 × 10⁻⁵ hectares.
One hectare equals 1,000,000 square decimeters.
