What is kilowatt-hour (kWh)? One kilowatt-hour is defined as the energy consumed by power consumption of 1kW during 1 hour: 1 kWh = 1kW ⋅ 1h. One kilowatt-hour is equal to 3.6⋅106 joules: 1 kWh = 3.6⋅106 J. The energy E in kilowatt-hour (kWh) is equal to the power P in kilowatts (kW), times the time t in hours (h).

Watt second A watt second (also watt-second, symbol W s or W·s) is a derived unit of energy equivalent to the joule.[1] The watt-second is the energy equivalent to the power of one watt sustained for one second. While the watt-second is equivalent to the joule in both units and meaning, there are some contexts in which the term watt-second is used instead of joule. The kilowatt hour (kWh) is equivalent to 3,600,000 watt-seconds and is a unit used in the electricity market, and by producers of electricity.

How Much is a Kilowatt Hour? Top 10 amazing movie makeup transformations. A kilowatt hour is a unit of energy, and the typical way that electricity is measured. A kilowatt (kW) is 1,000 watts (w), and a kilowatt hour refers to the use of a device or a set of devices that use 1,000 watts for one hour. Using a 100 watt light-bulb for 10 hours would equal 1 kilowatt hour (kWh), as would the use of a 10,000 watt machine for 6 minutes. A watt or kilowatt is a measure of power, or how much electricity is being used by a device at a particular moment.

What is a Watt, Anyway? Understanding Energy and Power Metrics Watts measure power--kilowatt-hours measure energy. When you get your utility bill, the electricity you've used is measured in kilowatt -hours (kWh). While a watt is a measure of power, a kWh is a measure of energy. Energy is defined as the capacity to do work, such as creating heat, light, or motion. If you run a 60-watt lightbulb for one hour, you've used 60 watt-hours, or 0.06 kilowatt-hours, since a kWh is 1,000 watt-hours.
