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 light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space ..more definition+
