To convert joules (J) to volts (V), you need to know the charge in coulombs (C). The formula to convert joules to volts is:
Volts=Joules/Coulombs
For these calculations, let's assume a standard charge of 1 coulomb (C) for simplicity.
Below is a table showing the conversion of various joules values to volts. sorted from smallest to largest, assuming a charge of 1 coulomb (C).

To convert 1 joule to volts with a charge of 1 coulomb:
Volts=1/1=1 V
To convert 100 joules to volts with a charge of 1 coulomb:
Volts=100/1=100 V
To convert 200 joules to volts with a charge of 1 coulomb:
Volts=200/1=200 V
