How to Convert Astronomical Units to Nanometers
The astronomical unit and nanometer are both units of length. By definition, 1 astronomical unit equals exactly 1.496e20 nanometers. This means to convert astronomical units to nanometers, you multiply by 1.496e20.
Formula
Step-by-Step Example
Convert 5 AU to nanometers:
We need to convert astronomical units to nanometers
Since 1 AU = 1.496e20 nm, multiply by 1.496e20
5 × 1.496e20 = 7.48e20
5 AU = 7.48e20 nm

About These Units
Astronomical Unit (AU)
An astronomical unit (AU) is the average distance from Earth to the Sun: approximately 149.6 million kilometers or 93 million miles. AUs measure distances within our solar system. Mars is 1.52 AU from the Sun, Jupiter is 5.2 AU.
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.
