Electrochemical Cell Potential (Nernst) Calculator
Compute standard cell potential (E°cell) from reduction potentials and non-standard voltage via the Nernst equation.
e.g. Cu²⁺ + 2e⁻ → Cu (+0.34 V)
e.g. Zn²⁺ + 2e⁻ → Zn (-0.76 V)
Standard Cell Potential (E°_cell = E°_cat - E°_an)

How to Use
- Enter the cathode standard potential and anode standard potential.
- Select Standard Cell Potential to view the standard cell potential (e°_cell = e°_cat - e°_an).
