the pound key on a telephone keyboard is called 'dièse' in French because it resembles the musical mark of the same name (in English: sharp sign). Pronounciation: 'dee-az'
Many sources say it is because # is the sign sometimes used after a number to represent pound as a measure of weight (more commonly expressed as lb).
