How to convert kilometers to fermis
1 kilometer is equal to 1 × 10¹⁸ fermis, and 1 fermi is equal to 1 × 10⁻¹⁸ kilometers. To convert, multiply by the conversion factor:
fermis = kilometers × 1 × 10¹⁸
fermis = kilometers ÷ 1 × 10⁻¹⁸Example: convert 1 km to fm: 1 × 1 × 10¹⁸ = 1 × 10¹⁸ fm.

About the kilometer
A kilometer is 1,000 meters. It's the standard unit for distances between places, road signs and running races in most countries.
Symbol: km · 1 km = 1,000 m · Category: Metric (SI)
About the fermi
The fermi is the traditional name in nuclear physics for the femtometer (10⁻¹⁵ m), named after physicist Enrico Fermi.
