Convert Nanometers to kilometers
1 nanometer = 1.000000e-12 kilometers · km = nm ÷ 1,000,000,000,000
When you need this conversion
This conversion goes from nanometers, the scale of semiconductors and light wavelengths, to kilometers, the metric unit for road distances and travel. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.

The formula
km = nm ÷ 1,000,000,000,000Because both units measure length, the conversion is a single multiplication by a fixed factor. That factor never changes, so the result is exact.
