Volts is a measure of Electrical Potential (such as the potential difference between two wires, for example).
kiloWatt-hours (kWh) is a measure of energy, and is the unit you might be familiar with on an electric bill.
These two units are measure two different things and cannot be converted without more information.
A watt is a unit of power. 1000 watts is 1 kilowatt (kW).
If a constant power of 1 kilowatt is consumed for 1 hour, 1 kilowatt-hour (kWh) of energy is consumed.
Electrical power can be computed (amongst other ways) by multiplying the voltage across a circuit by the current through the circuit.
Power = volts * amps
According to Ohm's laws,
V = R * I
The voltage (v) across a circuit is directly related to the current (I) through the circuit by the resistance (R).
If you know the voltage (v) and the resistance (R) you can calculate the power of the circuit. If you know the time as well, you can then find the energy consumption.

kwh is found by the formula volts x amps divided by 1000 x hours. That is for dc circuits. In an ac circuit it is volts x amps divided by 1000 x power factor x hours. The electric meter on your house does all of that for you.

You can't really convert volts into kilowatt hours without knowing the amperes. You might need to rephrase your question, and put it in context.

They are two different things and not related...
