How to Convert Astronomical Units to Femtometers
The astronomical unit and femtometer are both units of length. By definition, 1 astronomical unit equals exactly 1.496e26 femtometers. This means to convert astronomical units to femtometers, you multiply by 1.496e26.
Formula
Step-by-Step Example
Convert 5 AU to femtometers:
We need to convert astronomical units to femtometers
Since 1 AU = 1.496e26 fm, multiply by 1.496e26
5 × 1.496e26 = 7.48e26
5 AU = 7.48e26 fm

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.
Femtometer (fm)
A femtometer (fm), also called fermi, is a metric unit equal to 10⁻¹⁵ meters or one quadrillionth of a meter. Femtometers measure atomic nuclei (1-10 fm), proton radius (0.87 fm), and nuclear forces. Named after physicist Enrico Fermi.
