Joules to Volts calculator

Enter the energy in joules (J), electric charge in coulombs (C), then press the Calculate button to get the result in volts (V).

Joules to Volts calculation

Energy in J
Electric charge in coulombs (C)

V(V) = E(J) / Q(C)

The voltage V in volts (V) is equal to the energy E in joules (J), divided by the electric charge Q in coulombs (C).
