| Sample | Converted |
|---|---|
| 1 km² | 1.000000e+10 cm² |
| 5 km² | 5.000000e+10 cm² |
| 10 km² | 1.000000e+11 cm² |
| 100 km² | 1.000000e+12 cm² |
| 1,000 km² | 1.000000e+13 cm² |
This conversion scales values from a larger area unit to a smaller one. That usually increases the numeric value when going from km² to cm².
