How to Convert Femtometers to Astronomical Units
The femtometer and astronomical unit are both units of length. By definition, 1 astronomical unit equals exactly 1.496e26 femtometers. This means to convert femtometers to astronomical units, you divide by 1.496e26.
Formula
Step-by-Step Example
Convert 5 fm to astronomical units:
We need to convert femtometers to astronomical units
Since 1 AU = 1.496e26 fm, divide by 1.496e26
5 ÷ 1.496e26 = 3.3422459893e-26
5 fm = 3.3422459893e-26 AU

About These Units
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.
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.
