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+
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 Light Seconds (ls) is equal to 299800000 meters, while 1 Fermi (fermi) = 1.0E-15 meters.9687529674 Light Seconds | to common length units |
