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 siriometer is a rarely used and an obsolete astronomical unit of length, defined to be equal to about one million astronomical units (au). One siriometer is approximately 149.6 petametres; 4.848 parsecs; 15.8 ..more definition+
