For the purpose of instruction, use 5 kilowatts for your base.
If you have 5 kilowatts of electricity multiplied by 1 hour, you would have consumed 5 kilowatt-hours of energy. If you have 5 kilowatts of electricity multiplied by 4 hours, you would have consumed 20 kilowatt-hours of energy
Because the kilowatt is a component of the kilowatt-hour, the numbers are not converted; they must be calculated each time.
