what is kwh in electricity bill

A kWh (kilowatt-hour) is a unit of measure calculated to determine how many kilowatts an electric device uses per hour. It is the amount of power (watts) something uses if left on for an hour, divided by 1000 (kilo) . Your electric meter records how much electricity you use in kilowatt-hours (kWh) . When you look at your electricity bill, you will see the total number of kWhs you used in the month. Your utility or electric provider charges you an “electric rate”. You pay a few cents for every kWh that you use. An average house uses about 900 kWh each month. To calculate the electricity usage of each appliance or device, you’ll need the following: the wattage of the appliance, the average number of hours you use it per day, and the price you pay per kilowatt-hour (kWh) of electricity.
