To convert square nanometers to square kilometers, multiply the value by 1 × 10⁻²⁴. To go the other way, multiply square kilometers by 1 × 10²⁴ to get square nanometers.
| Square Nanometers (nm²) | Square Kilometers (km²) |
|---|---|
| 1 nm² | 1 × 10⁻²⁴ km² |
| 2 nm² | 2 × 10⁻²⁴ km² |
| 5 nm² | 5 × 10⁻²⁴ km² |
| 10 nm² | 1 × 10⁻²³ km² |
| 20 nm² | 2 × 10⁻²³ km² |
| 50 nm² | 5 × 10⁻²³ km² |
| 100 nm² | 1 × 10⁻²² km² |
| 500 nm² | 5 × 10⁻²² km² |
| 1,000 nm² | 1 × 10⁻²¹ km² |
25 nm² × 1 × 10⁻²⁴ = 2.5 × 10⁻²³ km²
Try this example →250 nm² × 1 × 10⁻²⁴ = 2.5 × 10⁻²² km²
Try this example →Square nanometer (nm²). A square nanometer is 10⁻¹⁸ m², used in nanotechnology and chip design.
Square kilometer (km²). A square kilometer is one million square meters (100 hectares), used for countries, cities and lakes.
There are 1 × 10⁻²⁴ square kilometers in one square nanometer.
Multiply the number of square nanometers by 1 × 10⁻²⁴. For example, 10 square nanometers equal 1 × 10⁻²³ square kilometers.
One square kilometer equals 1 × 10²⁴ square nanometers.
