To convert square kilometers to square decimeters, multiply the value by 100,000,000. To go the other way, multiply square decimeters by 1 × 10⁻⁸ to get square kilometers.
| Square Kilometers (km²) | Square Decimeters (dm²) |
|---|---|
| 1 km² | 100,000,000 dm² |
| 2 km² | 200,000,000 dm² |
| 5 km² | 500,000,000 dm² |
| 10 km² | 1,000,000,000 dm² |
| 20 km² | 2,000,000,000 dm² |
| 50 km² | 5,000,000,000 dm² |
| 100 km² | 10,000,000,000 dm² |
| 500 km² | 50,000,000,000 dm² |
| 1,000 km² | 100,000,000,000 dm² |
25 km² × 100,000,000 = 2,500,000,000 dm²
Try this example →250 km² × 100,000,000 = 25,000,000,000 dm²
Try this example →Square kilometer (km²). A square kilometer is one million square meters (100 hectares), used for countries, cities and lakes.
Square decimeter (dm²). A square decimeter is 100 square centimeters (0.01 m²).
There are 100,000,000 square decimeters in one square kilometer.
Multiply the number of square kilometers by 100,000,000. For example, 10 square kilometers equal 1,000,000,000 square decimeters.
One square decimeter equals 1 × 10⁻⁸ square kilometers.
