The shannon (symbol Sh) is a unit of information and of entropy defined by IEC 80000-13. One shannon is the information content of an event when the probability of that event occurring is one half.[1] It is also the entropy of a system with two equiprobable states. One shannon is equivalent to one bit; see units of information.
The shannon is named after Claude Shannon.
