The symbol for the physical quantity mass/charge is ''m/q''. The former ''[[m/z]]'' is based on a missconception and should no longer be used. | The symbol for the physical quantity mass/charge is ''[[Talk:M/q|m/q]]''.

The SI unit of the physical quantity ''m/q'' is kilogram/coulomb ('''kg/C'''). | The SI unit of the physical quantity ''m/q'' is kilogram/coulomb ('''kg/C'''). | ||

'''u''' is | For simplicity, '''u''' is better called [[Dalton]] ('''Da''') and '''e''' is called [[Millikan]] ('''Mi'''). | ||
'''u'''/'''e''' is sometimes called [[Thomson]] ('''Th'''). | |||

Hence, a [[Mass Spectrum | mass spectrum]] x-axis should be labeled as either of the below: | |||
* ''m/q'' ('''u'''/'''e''') | * ''m/q'' ('''u'''/'''e''') | ||
* ''m/q'' ('''Da'''/''' | * ''m/q'' ('''Da'''/'''Mi''') | ||
