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.
A kilowatt (kW) is a unit of power equal to 1,000 watts. It measures the rate at which energy is used or generated, with one watt representing one joule per second. In terms of energy consumption, one kilowatt-hour (kWh) equals the energy used by a 1 kW device running for one hour.
Considering it is kw for kilowatt and not kv. 1 megawatt = 1000 kilowatt.

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.
1 joule = 1 ws (watt-second); since 1 kw = 1000 w, and 1 h = 3600 seconds, it follows that 1 kwh = 3,600,000 ws or joule.
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 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.
