Units of electricity as given on power bills are usually measured in kiloWatt hours. (kW.h) This is a kiloWatt of energy delivered for a period of an hour. It is a unit of power, and a kiloWatt is a measure of energy.
One unit of electricity is exactly equal to 1000 Watts of power used for 1 hour.
Kilowatts measure power, that is how fast the energy is used. Energy is measured by power times time, so kilowatts times hours is equal to kilowatt hours, also called Units.
The metric system uses differing prefixes to show multiples of ten for base units. To indicate one thousand units, the prefix kilo- is used, as in kilometer, or kilowatt.
1 kilowatt = 1000 joules per second, so it will take 480 seconds. (8 minutes).

This is a trick question. You need to know the amount of water & the temperature.
Spelled kilowatt, it is a unit of measurement used to describe the amount of power consumed or provided in an electrical system. The equation is P = VA and P = VApf for AC systems. A kilowatt is 1000 Watts. Spelled kilowatt, it is a unit of measurement used to describe the amount of power consumed or provided in an electrical system. The equation is P = VA and P = VApf for AC systems. A kilowatt is 1000 Watts.
1 kilowatt-hour is 3412 British Thermal Units, so 4 kWh is 13648 BTU.
Electric energy is measure in Units which are kilowatt-hours. Your electricity meter records the usage in Units over the billing period. The meter measures the true power and not the volts times the amps.
Kilowatt hours.

Kilowatt has no reference to time. Kilowat hour has one hour.
The electric meter uses kWh (kilowatt x hours) as units; a Joule is a watt x second. Therefore, a kWh has 3.6 million joules. Just multiply by this number.
Ten to fifteen 1000 watt baseboard heaters is equal to a 10 or 15 kilowatt electric furnace.
The electric companies charge a homeowner on the basis of a kilowatt hour.
Gigawatts and kilowatts are units of power, and 1 gigawatt = 1 million kilowatts. Energy is measured in kilowatt-hours or gigawatt-hours, 1 gigawatt-hour = 1 million kilowatt-hours.
Watt, kilowatt, or megawatt are units of power (energy/time). A watt is 1 joule/second. A kilowatt is a thousand joules per second. A kilowatt is also 1 kWh/hour (kilowatt-hour / hour). Since you would usually pay per kilowatt-hour, you might be more interested in the number of kilowatt-hours. A megawatt is a million joules per second - or a thousand kWh/hour.
