How to convert kilometers to nanometers
One kilometer equals 10,00,00,00,00,000 nanometers, so multiply the number of kilometers by 10,00,00,00,00,000.
nm = km × 10,00,00,00,00,000
1 km = 10,00,00,00,00,000 nm · 1 nm = 1 × 10⁻¹² km
Worked example
To convert 5 kilometers to nanometers: 5 km × 10,00,00,00,00,000 = 50,00,00,00,00,000 nm.
About kilometers (km)
A kilometer is 1,000 metres. Road distances and speed limits in India and most countries use kilometres.
About nanometers (nm)
A nanometer is one billionth of a metre. It is used for wavelengths of light and the size of molecules and computer chip features.
