Nanometers to kilometers Conversion
1 nanometers (nm) is equal to 0.000000000001 kilometers (km).
1 nm = 0.000000000001 km
or
1 km = 1000000000000 nm
Formula
To convert a length from nanometers (nm) to kilometers (km), divide the length in nanometers by 1000000000000
l(km) = l(nm) / 1000000000000
Examples:
Convert 500 nanometers to kilometers:
l(km) = 500nm / 1000000000000 = 0.0000000005 km

Frequently asked questions
How do I convert nanometers to kilometers?
Divide the value in nanometers by 1000000000000 to get the result in kilometers. For example, 5 nm ÷ 1000000000000 = 5e-12 km.
How many kilometers are in 1 nanometers?
1 nanometers (nm) is equal to 1e-12 kilometers (km).
How do I convert kilometers back to nanometers?
Use the inverse operation: multiply the value in kilometers by 1000000000000 to get the result in nanometers.
How accurate is the nanometers to kilometers conversion?
The converter multiplies by the conversion factor 1000000000000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
