To convert kilometers to nanometers, multiply the value by 1,000,000,000,000. To go the other way, multiply nanometers by 1 × 10⁻¹² to get kilometers.

25 km × 1,000,000,000,000 = 25,000,000,000,000 nm
Try this example →250 km × 1,000,000,000,000 = 250,000,000,000,000 nm
Try this example →Kilometer (km). A kilometer is 1,000 meters and the standard unit for road distances in most countries, including India.
Nanometer (nm). A nanometer is one billionth of a meter, used for wavelengths of light and the size of molecules.
There are 1,000,000,000,000 nanometers in one kilometer.
Multiply the number of kilometers by 1,000,000,000,000. For example, 10 kilometers equal 10,000,000,000,000 nanometers.
One nanometer equals 1 × 10⁻¹² kilometers.
12,000,000,000,000 nanometers. Other common values: 5 kilometers = 5,000,000,000,000 nanometers and 100 kilometers = 100,000,000,000,000 nanometers.
