How to convert nanometers to kilometers
There are 10,00,00,00,00,000 nanometers in one kilometer, so divide the number of nanometers by 10,00,00,00,00,000.
km = nm ÷ 10,00,00,00,00,000
1 nm = 1 × 10⁻¹² km · 1 km = 10,00,00,00,00,000 nm
Worked example
To convert 5 nanometers to kilometers: 5 nm ÷ 10,00,00,00,00,000 = 5 × 10⁻¹² km.
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.
About kilometers (km)
A kilometer is 1,000 metres. Road distances and speed limits in India and most countries use kilometres.
