Electrode potential, E, in electrochemistry, according to an IUPAC definition, is the electromotive force of a cell built of two electrodes:
* on the left-hand side is the standard hydrogen electrode, and
* on the right-hand side is the electrode the potential of which is being defined. By convention: ECell := ECathode − EAnode From the above, for the cell with the standard hydrogen electrode (potential of 0 by convention), one obtains: ECell = ERight − 0 = EElectrode Electrode potential is measured in volts (V).

abstract
| - Electrode potential, E, in electrochemistry, according to an IUPAC definition, is the electromotive force of a cell built of two electrodes:
* on the left-hand side is the standard hydrogen electrode, and
* on the right-hand side is the electrode the potential of which is being defined. By convention: ECell := ECathode − EAnode From the above, for the cell with the standard hydrogen electrode (potential of 0 by convention), one obtains: ECell = ERight − 0 = EElectrode The left-right convention is consistent with the international agreement that redox potentials be given for reactions written in the form of reduction half-reactions. Electrode potential is measured in volts (V).
