Kilowatthour is a unit of energy equivalent to one kilowatt of power sustained for one hour. It is commonly used for measuring and billing electricity consumption. The symbol for kilowatt-hour is kWh. One kilowatt is equal to 1,000 watts. Therefore, a kilowatt-hour represents 1,000 watts of power used for one hour.

The kilowatt-hour is a unit of energy, not power. Power is the rate at which energy is used or transferred, while energy is the total amount of work done or heat transferred. For instance, a 100-watt light bulb consumes 100 watts of power. If it is left on for 10 hours, it will consume 1 kilowatt-hour of energy (100 watts * 10 hours = 1000 watt-hours = 1 kWh).

Electric utility companies typically measure and bill customers for their electricity usage in kilowatt-hours. Electricity meters installed in homes and businesses record the cumulative amount of energy consumed. The cost of electricity is then calculated by multiplying the total kilowatt-hours used by the price per kilowatt-hour set by the utility provider. Understanding kilowatt-hours helps consumers gauge their energy consumption and manage their electricity bills.
