1 Fermi is a quadrillionth of a metre ie 1 Fermi = 10-12 metre.
fermi
One fermi is one femtometer, which is equal to 10-15 meters, or 0.000,000,000,000,001 meters.
I am sure there are lots of questions from Fermi, but I'll bet you mean the Fermi Paradox, which asks, "If there are ETs, where are they?" What he meant by this, is that the time to completely colonize the galaxy is very small compared to the age of the galaxy, so there should be ETs here if they exist at all!" So where are they--or alternatively what is wrong with this idea? For more on this please search "Fermi Paradox".

1 Fermi is a quadrillionth of a metre ie 1 Fermi = 10-12 metre.
1 fermi = 1 quadrillionth of a metre.
1 fermi is equal to 1 × 10^-15 meters, and 1 nanometre is equal to 1 × 10^-9 meters.
The Fermi level is also known as the electron chemical potential (μ), and is a constant appearing in the Fermi-Dirac distribution formula: F() = 1 / [1 + exp((-μ)/kT)] Even though the gap may not contain any electronic states, there may be some thermally excited holes in the valence band and electrons in the conduction band, with the occupancy given by the Fermi-Dirac (FD) function. By inspecting the FD function, it becomes clear that if a state existed at the Fermi level, it would have an occupancy of 1/[1 + exp(0)] = 1/[1+1] = 1/2. Lastly, do not confuse Fermi level with Fermi energy. One is the chemical potential of electrons, the other is the energy of the highest occupied state in a filled fermionic system. In semiconductor physics, the Fermi energy would coincide with the valence band maximum.
The spelling Fermi is an Italian surname, notably physicist Enrico Fermi (1901-1954).
Laura Fermi, an American author and wife of physicist Enrico Fermi, passed away on December 26, 1977.
EUR Fermi was created in 1955.
Laura Fermi was born in 1907.
Enrico Fermi had two siblings one sister and one brother: Maria and Giulio Fermi.
A fermi gas is a model from quantum mechanics first proposed by Fermi. A neutron star is said to be an example of a Fermi gas, and that would indeed be a dangerous place.
The Fermi is a unit of length in particle physics, equivalent to approximately 10^-15 meters or 1 femtometer. It is used to describe the scale at which particles interact at the subatomic level.
