Best Answer

To calculate an answer, first multiply the watts used by the hours of use. This will give you watt hours. Now divide your answer by 1000 and this will give you kWh of use. Take the kWh of use and multiply it by the cost per kilowatt that your utility company charges you per kilowatt hour. This information can be found on your electric bill or you can give them a call and ask how much they charge you per kilowatt hour.
