Nanometres to kilometres converter
Kilometres (km)
1 nanometre = 1e-12 kilometres
How to convert nanometres to kilometres
km = nm × 1 × 10^-12
Multiply the number of nanometres by 1 × 10^-12 to get kilometres. Going the other way, divide by 1 × 10^-12 (or multiply by 1000000000000).
One nanometre is exactly defined as 1 × 10^-12 kilometres (to 12 significant figures), and one kilometre is 1000000000000 nanometres.
Worked examples
- Convert 5 nanometres: 5 × 1 × 10^-12 = 5e-12 5e-12 kilometres.
- Convert 12.5 nanometres: 12.5 × 1 × 10^-12 = 1.25e-11 1.25e-11 kilometres.
- Convert 250 nanometres: 250 × 1 × 10^-12 = 2.5e-10 2.5e-10 kilometres.
