Convert Parsec to Femtometer
Type the number of parsecs that you wish to convert to femtometers.
How to Convert Parsecs to Femtometers
The parsec and femtometer are both units of length. By definition, 1 parsec equals exactly 3.086e31 femtometers. This means to convert parsecs to femtometers, you multiply by 3.086e31.
Formula
Step-by-Step Example
Convert 5 pc to femtometers:
We need to convert parsecs to femtometers
Since 1 pc = 3.086e31 fm, multiply by 3.086e31
5 × 3.086e31 = 1.543e32
5 pc = 1.543e32 fm

About These Units
Parsec (pc)
A parsec (pc) is an astronomical unit equal to approximately 3.26 light years or 3.086×10¹⁶ meters. Parsecs measure stellar and galactic distances using parallax. The Milky Way galaxy is about 30,000 parsecs in diameter. Kiloparsecs (kpc) and megaparsecs (Mpc) measure larger cosmic distances.
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.
