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 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
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
1 joule is equivalent to the energy transferred when a force of 1 newton is applied over a distance of 1 meter. It is also equivalent to 0.239 calories or 0.0002778 kilowatt-hours.
There are 3,600,000 joules of energy in 1 kilowatt-hour.
There are 3.6 million joules of energy in 1 kilowatt-hour (kWh).
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.
Joules x 0.000000278 = kW/h
-- watt -- kilowatt -- joule per second -- horsepower
1 joule is equal to 10^7 ergs.
1 kilowatt = 1000 watt ==> 1 watt = 0.001 kilowatt
