Volts to Joules Calculator

It is a conversion calculator used to convert the electrical voltage in volts to the energy in joules. It is simple to use and requires you to enter the value in volts and coulombs in their required text fields. Once the correct figures are filled in the cells, click on the ‘Calculate' button to complete the conversion process. Always be keen when entering the values since the calculator will give the correct results depending on the accuracy of the input. The result in joules is displayed below the ‘Calculate' and ‘Reset' buttons.

Formula for calculating the Volts (V) to Joules (J)

E (J) = V (V) x Q (C), which means that the energy in Joules is calculated by multiplying the voltage in volts by the electrical charge in coulombs.

It can also be expressed as Joule = volt x coulomb or J = V x C

For example;
If the voltage supply of an electrical circuit is 35 V and the charge flow is 7 Coulombs, what is the energy in joules?


= 35 V x 7 C = 245 Joules (J).

The same procedure can always be repeated if you want to perform new calculations. It is also important to know that the Volts to Joules calculator cannot perform more than one conversion at a time. However, you can always coordinate the ‘Calculate' and ‘Reset' button when performing new calculations. The ‘Calculate' control allows you to initiate the conversion and it takes less than a second for you to get the results. The Reset button will be useful in erasing all the previous data from the text fields providing new space for more calculations. The fact that it is a free online calculator means that you can use it anytime and it gives accurate results based on the correct values entered before conversion.
