When a electrical appliances whose power usage is X watts is run for Y seconds it uses X×Y joules of energy. The energy unit used by electrical utilities in their monthly bills is the kilowatt-hour (kwh, that is, 1 kilowatts used for 1 hour) how many joules are there in a kilowatt hour? If electricity cost per $0.09 per kilowatt hour, how much does it cost per megajoule?
