The hartley (symbol Hart) is a unit of information defined by International Standard IEC 80000-13 of the International Electrotechnical Commission, which is equal to and supersedes the ban. One hartley is the information content of an event if the probability of that event occurring is 1/10.[1] It is therefore equal to the information contained in one decimal digit (or dit), assuming a priori equiprobability of each possible value.
Though not an SI unit, the hartley is part of the International System of Quantities. It is named after Ralph Hartley.
