To convert nanometers to kilometers, multiply the value by 1 × 10⁻¹². To go the other way, multiply kilometers by 1,000,000,000,000 to get nanometers.
| Nanometers (nm) | Kilometers (km) |
|---|---|
| 1 nm | 1 × 10⁻¹² km |
| 5 nm | 5 × 10⁻¹² km |
| 10 nm | 1 × 10⁻¹¹ km |
| 25 nm | 2.5 × 10⁻¹¹ km |
| 50 nm | 5 × 10⁻¹¹ km |
| 100 nm | 1 × 10⁻¹⁰ km |
| 250 nm | 2.5 × 10⁻¹⁰ km |
| 500 nm | 5 × 10⁻¹⁰ km |
| 1,000 nm | 1 × 10⁻⁹ km |
| 2,500 nm | 2.5 × 10⁻⁹ km |
| 5,000 nm | 5 × 10⁻⁹ km |
| 10,000 nm | 1 × 10⁻⁸ km |
| 100,000 nm | 1 × 10⁻⁷ km |
| 1,000,000 nm | 1 × 10⁻⁶ km |
Nanometer (nm). A nanometer is one billionth of a meter, used for wavelengths of light and the size of molecules.
Kilometer (km). A kilometer is 1,000 meters and the standard unit for road distances in most countries, including India.
There are 1 × 10⁻¹² kilometers in one nanometer.
Multiply the number of nanometers by 1 × 10⁻¹². For example, 10 nanometers equal 1 × 10⁻¹¹ kilometers.
One kilometer equals 1,000,000,000,000 nanometers.
1 × 10⁻⁹ kilometers. Other common values: 100 nanometers = 1 × 10⁻¹⁰ kilometers and 10,000 nanometers = 1 × 10⁻⁸ kilometers.
