The abbreviation ''m/z'' is used to denote the dimensionless quantity formed by dividing the [[mass number]] of an ion by its [[charge number]]. It has long been called the [[mass-to-charge ratio]] although m is not the ionic mass nor is z a multiple or the elementary (electronic) charge, e. The abbreviation [[m/e]] is, therefore, not recommended. Thus, for example, for the ion C<sub>7</sub>H<sub>7</sub><sup>2+</sup>, ''[[m/z]]'' equals 45.5..

Mass/charge ratio

The abbreviation m/z is used to denote the dimensionless quantity formed by dividing the mass number of an ion by its charge number. It has long been called the mass-to-charge ratio although m is not the ionic mass nor is z a multiple or the elementary (electronic) charge, e. The abbreviation m/e is, therefore, not recommended. Thus, for example, for the ion C7H72+, m/z equals 45.5..
