Quick Volts (V) to Joules (j) Conversion Calculator
1 Volt is defined as energy consumption of one joule per electric charge of one coulomb. 1 eV in joules (symbol J) is equivalent to the numerical value of the charge of an electron in coulombs (symbol C).

Note, For higher values like 5×10^{3}, 10×10^{6}, 1.6 x10^{12}, enter the value like this for scientific notation as 5e3, 10e6, 1.6e12, etc.
Conversion Using the Power Formula :
Volts to Joules Calculation:
The Energy (E) in joules (J) is equal to the voltage V in volts (V), times the electrical charge Q in coulombs (C):
For example, let’s convert a charge of 5 coulombs at 24 volts to joules.
E_{(J)} = 24 x 5
V_{(V)} = 120 V
Where:

 E = Energy in Joules (j)
 V = Voltage in volts
 Q = Electric Charge (C)

Frequently asked questions
Ampere = 1 Coulomb / Second.
A Voltage for each circuit element in a series circuit can be calculated by applying Ohm's law: V=R*I.
A body is said to have 1 watt of power if it can perform 1 joule of work in 1 second.
The wattage in one amp depends on the voltage of the system. Using the formula for DC conversion: Watts = Amps x Volts, at 120 volts, 2 amps would equal 240 watts.
1 kilowatthour (1 kWh) is equivalent to a power of 1 kW being used for 1 hour, or 0·5 kW for 2 hours, 2 kW for 0·5 hours, etc.
