Joules to Voltage Calculator


A Joules to Voltage calculator is a online calculating tool for converting joules of energy to electrical voltage.

Joules (J) are units of energy and voltage (V) are units of electrical potential difference, respectively. The conversion between these two units is determined by the electrical system & the type of energy in consideration.

A practical, automatic, and simple calculator to convert from Joules to Volts.

Joules to Volts conversion formula:

V = E/Q

Volts: The volt is a measurement unit derived from voltage, electric potential difference, or both.
Joule: Its sign is J, and it denotes unit for an energy.

Coulomb: It is the  unit of electric charge (Q).

The voltage V in volts (V) is obtained by dividing the energy E in joules (J) by the charge Q in coulombs (C)
