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.
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 ..more definition+
