The **kilowatt-hour** (symbol **kWh**) is a derived unit of energy equal to 3.6 megajoules.

If the energy is being transmitted or used at a constant rate (power) over a period of time, the total energy in **kilowatt-hours** is the power in kilowatts multiplied by the time in hours. The kilowatt-hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.

All the SI prefixes are commonly applied to the watt-hour: a **kilowatt-hour** is 1,000 W·h; a megawatt-hour is 1 million W·h; a milliwatt-hour is 1/1000 W·h and so on.

The **kilowatt-hour** is commonly used by electrical distribution providers for purposes of billing, since the monthly energy consumption of a typical residential customer ranges from a few hundred to a few thousand kilowatt-hours.
