To convert square kilometers to square micrometers, multiply the value by 1 × 10¹⁸. To go the other way, multiply square micrometers by 1 × 10⁻¹⁸ to get square kilometers.
| Square Kilometers (km²) | Square Micrometers (µm²) |
|---|---|
| 1 km² | 1 × 10¹⁸ µm² |
| 2 km² | 2 × 10¹⁸ µm² |
| 5 km² | 5 × 10¹⁸ µm² |
| 10 km² | 1 × 10¹⁹ µm² |
| 20 km² | 2 × 10¹⁹ µm² |
| 50 km² | 5 × 10¹⁹ µm² |
| 100 km² | 1 × 10²⁰ µm² |
| 500 km² | 5 × 10²⁰ µm² |
| 1,000 km² | 1 × 10²¹ µm² |
25 km² × 1 × 10¹⁸ = 2.5 × 10¹⁹ µm²
Try this example →250 km² × 1 × 10¹⁸ = 2.5 × 10²⁰ µm²
Try this example →Square kilometer (km²). A square kilometer is one million square meters (100 hectares), used for countries, cities and lakes.
Square micrometer (µm²). A square micrometer is 10⁻¹² m², used for cells and microscopic structures.
There are 1 × 10¹⁸ square micrometers in one square kilometer.
Multiply the number of square kilometers by 1 × 10¹⁸. For example, 10 square kilometers equal 1 × 10¹⁹ square micrometers.
One square micrometer equals 1 × 10⁻¹⁸ square kilometers.
