In physics, the Planck length, denoted ℓP, is a unit of length, equal to 1.616229(38)×10−35 meters. It is a base unit in the system of Planck units, develo ..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.
