A 'unit' is exactly equivalent to one kilowatt hour, and is used in Britain as the unit of measurent for purchasing electrical energy. The term, 'unit', is short for 'Board of Trade Unit'. The Board of Trade was a government organisation that used to regulate the cost of electricity. The cost of a unit of energy depends on your supply company and the tariff you have chosen.

∙ 11y ago1 kilowatt is 1000 watts, a measure of power, which is the rate at which energy is converted. Energy is measured in kilowatt-hours.
(the question is the same as asking: 'how far is a knot?')
But a kilowatt running for 1 hour converts 1 kilowatt-hour. If running for 10 hours it is 10 kilowatt-hours.
Hope that helps.

How is the cost of electrical energy consumption computed?
The cost of electrical energy is computed per energy unit. The more energy you use, the more you will be charged. The unit normally used is the kWh (kilowatt-hour), which is equal to 3,600,000 watt-seconds or joules.The cost per kWh is, at least roughly, determined by supply and demand.
How much electrical energy is transferred by a 2000W cooker in half an hour?
1000 watt-hours.
What is SI and commercial unit of energy?
The SI unit of energy is Joules The commercial unit of energy is KiloWaltHour(KWh) The relationship between SI unit and commercial unit is: 1 KWh=3.6*106J (or 3600000 J) One KiloWaltHour is: 1kWh = 1kW * 1h And the definition for kWh is: 1kWh is the electric energy consumed by an appliance of power 1 whenit is used for one hour
What happened to energy when an appliances is used for a longer time?
Typically, an electrical appliance uses electrical energy at a certain rate (a certain power, a certain amount of energy per second). The longer you keep it on, the more energy it will use in total. The relation is simply: energy = power x time Units might be joule, watt, and seconds; or kWh, kW, and seconds.
What is the symbol for potential energy?
Electrical power is measured in Watts, or multiples of Watts, like kilowatts or megawatts. Electrical energy is power x time, usually kilowatthours or megawatthours.(kWh or MWh)
What is the unit used in selling electrical energy to consumers?
The kWh (kilowatt-hour)
Difference between kw and kwh?
KW is the unit power KWh is the unit of electrical energy KW or Watt defines the rating or power of a electrical equipment. For ex: motors, heaters etc. KWh is a measurement that how much energy is been consumed by the electrical equipments. Generally, operating 1KW rated equipment for an hour measures one KWh. Energy meters are the instruments for this purpose
What is kWh meter function?
Function of the KWH meter is to record the electrical energy.
What is a equation for electric energy?
electrical energy (in kWh) = electric power (in kWh) X time (in hours) E=Pt
How much electrical energy was produced by nuclear power plants?
2,598,000,000,000 kWh a year, that was estimated in 2008.
What is the electrical energy in kWh of a 2.4 kW air conditioning unit being used for 6 hrs?
Power is defined as follows:power = energy / time Therefore: energy = power x time Just multiply the power by the time. With the units used, the energy will be in kWh - no conversion required.
How is the cost of electrical energy consumption computed?

The unit most commonly used for measuring electrical energy consumption is the?
While the SI unit - and therefore, the recommended unit - for energy is the joule, energy used in households is more commonly measured in kWh. Since a joule is a watt-second, a kWh (kilowatt-hour) is equal to 3,600,000 joules.
How much electrical energy is transferred by a 2000W cooker in half an hour?
1000 watt-hours.
