Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 1.6e12, etc.
Conversion Using the Power Formula :
Joules to Volts Calculation:
The voltage V in volts (V) is equal to the energy (E) in joules (J), divided by the charge Q in coulombs (C):
For example, let’s Convert 15 joules of energy with a charge of 6 coulombs to volts.
V(V) = 15 ÷ 5
V(V) = 3 V
Where:
-
- V = Voltage in volts
- E = Energy in Joules (j)
- Q = Electric Charge (C)

Frequently asked questions
1 Volt is defined as energy consumption of 1 joule per electric charge of 1 coulomb. 1V = 1J/C.
The wattage in 1 amp depends on the voltage of the system. Using the formula for DC conversion: Watts = Amps x Volts, at 120 volts.
When spelled out, it means voltage (v) = current (A) x resistance (ohm), or volts = amps x ohms, or V = A x Ω.
How to Convert Watts, Amps, & Volts
Watts = Amps x Volts
Examples: 20 Amps x 220 Volts = 4400 Watts. 10 Amps x 240 Volts = 2400 Watts.
Joule is the unit of work done in the case of electric current, and coulomb is the unit of charge. Hence, joule/coulomb will be the unit of potential difference as it is the work done in moving unit charge from one point to another. So, 1 joule per coulomb = 1 volt = 1 V.
