Kilowatthours was created in 1998.
That is impossible. That are different things.
kilowatthours
This would be 30 watthours, or 0.030 kilowatthours
energy = power * time = 20w * 1hr = 20 watthours or 0.02 kilowatthours
kWh stands for kiloWatthours, the amount of electrical energy an appliance uses or generates in one hour measured in kiloWatts. It has nothing to do with one cubic metre of water.
Kilo = 1000. Watts the produce of Amps x Volts. One hour is not divided up into kilowatt hours, it is the use of 1000 watts over a period of one hour.
Watts means the electric power and kilowatthours means electric energy. Compare: http://en.wikipedia.org/wiki/Electric_power http://en.wikipedia.org/wiki/Power http://en.wikipedia.org/wiki/Electric_energy http://en.wikipedia.org/wiki/Energy Cheers ebs
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)
d. a kilowatthour meter. Electric energy used in homes is measured in kilowatthours, which is the unit for energy consumption. Kilowatthour meters measure the total amount of electricity consumed in a household over a period of time.
They sell electrical energy. They sell services. And they invest. Direct selling and wholeselling Mega-Watts to millions who need and survive off electricity! www.texascheapelectric.com
Power and energy consumption are terms used to describe the amount of electrical energy used in a specific period of time. Power is the rate at which energy is consumed, typically measured in watts, while energy consumption is the total amount of energy used over a given time, measured in watt-hours or kilowatt-hours.
To convert from KVA (kilovoltamperes) to KWH (kilowatthours) first convert to KW (kilowatts) by multiplying by power factor. Power factor is the cosine of the phase angle between voltage and current. Then multiply by the number of hours that you run the load.
