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. | The abbreviation ''m/z'' is used to denote the dimensionless quantity formed by dividing the [[mass number]] of an ion by its [[charge number]].
