How to Convert Light Years to Nanometers
The light year and nanometer are both units of length. By definition, 1 light year equals exactly 9.461e24 nanometers. This means to convert light years to nanometers, you multiply by 9.461e24.
Formula
Step-by-Step Example
Convert 5 ly to nanometers:
We need to convert light years to nanometers
Since 1 ly = 9.461e24 nm, multiply by 9.461e24
5 × 9.461e24 = 4.7305e25
5 ly = 4.7305e25 nm

About These Units
Light Year (ly)
A light year (ly) is the distance light travels in one year: approximately 9.461 trillion kilometers or 5.879 trillion miles. Light years measure interstellar distances. The nearest star Proxima Centauri is 4.24 light years away. Light travels 299,792 km/second.
Nanometer (nm)
A nanometer (nm) is a metric unit equal to one billionth of a meter or 0.001 micrometers. Nanometers measure visible light wavelengths (400-700 nm), DNA width (2 nm), computer chip transistors, and molecular structures. Essential in nanotechnology and semiconductor manufacturing.
