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 approxim ..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 Siriometer (sir) is equal to 1.496E+17 meters, while 1 Fermi (fermi) = 1.0E-15 meters.| 911500 Siriometer | to common length units |
