Conversion: Kilometers to Fermi
The base unit for length is meters (SI Unit)
[Kilometers] symbol/abbrevation: (km)
[Fermi] symbol/abbrevation: (fermi)

How to convert Kilometers to Fermi (km to fermi)?
1 km = 1.0E+18 fermi.
1 x 1.0E+18 fermi = 1.0E+18 Fermi.
Always check the results; rounding errors may occur.

Definition:

The kilometer (SI symbol: km) or kilometre (British spelling) is a unit of length in the metric system, equal to 1000 meters (kilo- being the SI prefix for 1000). It is the measurement unit used officially for e ..more definition+

A unit of length used to measure nuclear distances, = 10−15 meter. Named for the Italian physicist Enrico Fermi (1901–1954). Now obsolete, replaced by the SI term femtometer (symbol, fm); 1 fermi = 1 femtometer.

In relation to the base unit of [length] => (meters), 1 Kilometers (km) is equal to 1000 meters, while 1 Fermi (fermi) = 1.0E-15 meters.
