Analysis of information sources in references of the Wikipedia article "Shannon (unit)" in English language version.
The Système International d'unités recommends the use of the shannon (Sh) as the information unit in place of the bit to distinguish the amount of information from the quantity of data that may be used to represent this information. Thus, according to the SI standard, H(X) should actually be expressed in shannons. The entropy of one bit lies between 0 and 1 Sh.
