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 Zettameters (Zm) is equal to 1.0E+21 meters, while 1 Fermi (fermi) = 1.0E-15 meters.| 13 Zettameters | to common length units |
