1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
1 kilowatt = 1,000 watts1 watt = 1 joule per second1 hour = 3,600 seconds(1,500 kilowatt-hour) x (1,000 watt / kilowatt) x (1 joule / watt-second) x (3,600 second / hour) =(1,500 x 1,000 x 3,600) x (kilowatt - hour - watt - joule- second) / (kilowatt - watt - second - hour)= 5,400,000,000 joules
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.
Considering it is kw for kilowatt and not kv. 1 megawatt = 1000 kilowatt.
A watt is a unit of power. 1 watt = 1 joule/second; that is, if somebody consumes 1 watt, it consumes 1 joule of energy every second. Or if there is a transfer of 1 watt, 1 joule of energy is transferred every second. 1000 watts (1 kW), of course, is simply 1000 times as much (1000 joule/second).
1 watt = 1 joule per second 1 kilowatt = 1 kilojoule per second 750 kilowatt = 750 kilojoule per second
A kilowatt is 1000 watts, and 1 watt is 1 joule per second
A kilowatt, of course, is a thousand watts. Watt (and kilowatt) are units of power; 1 watt = 1 joule / second (where joule is the unit of energy). In general, the formula that relates them is: power = energy/time Which can also be written as: energy = power x time
Joules x 0.000000278 = kW/h
-- watt -- kilowatt -- joule per second -- horsepower
A thousand of what unit? 1 joule/second = 1 watt. 1000 joules/second = 1000 watts or 1 kilowatt.
It is a unit of energy. If energy is transferred at a rate (power) of one kilowatt, during one hour, then one kilowatt-hour (kilowatt times hour) of energy will be transferred. Since a joule is equal to a watt-second, a kilowatt-hour is the same as 3.6 million joules.
A joule is a watt-second, so one kilowatt for one second is a kilojoule.
This question has been answered in wikipedia:A joule is ...The work required to continuously produce one watt of power for one second; or one watt second (W·s) (compare kilowatt hour). This relationship can be used to define the watt.http:/en.wikipedia.org/wiki/JouleThe kilowatt hour, or kilowatt-hour, (symbol kW·h, kWh) is a unit of energy equal to 3,600,000 joules. Energy in watt hours is the multiplication of power in watts and time in hours.http:/en.wikipedia.org/wiki/Kilowatt_hour
Kilo is a prefix which means 1,000. So, the answer is 1000 watts.
