There's no such thing. "Kilowatt" is a rate of using or moving energy. Unless
you're doing something really weird and unusual in an electronics lab, you'd
never have any use for a "rate per hour".
Mathematically, I guess that unit is analogous to an acceleration. It would
describe how the rate of using energy is growing or shrinking. Its dimensions
would be " Force - distance/Time2 ". After 50 years in the business, I've honestly
never heard of it. That could mean that I've led a sheltered existence, but
I prefer to understand from it that I've simply never encountered anything
where it was needed.
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
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.
Multiply by kilovolts, and you will have it. For example: 1 amp hour X 0.120 kilovolts = 0.120 kilowatt hours
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
The energy 1 kilowatt-hour (kWh) is 3600000 joules.AnswerThere is no such thing as a 'kilowatt per hour'. You probably mean 'kilowatt hour'?
There is no such thing as a "kilowatt per hour". Kilowatt is a unit of power, not of energy. A unit of energy is kilowatt-hour. That's kilowatt times hours, not "per" hour ("per" implies division, not multiplication). If a generator produces 10 kilowatts, that means it produces 10 kilowatt-hours every hour.
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.
In North America it is kilowatt/hour. A kilowatt is 1000 watts. To find out how much your utility company charges you per kilowatt/hour, look on your utility bill. On my bill it is .08 cents for every kilowatt/hour that I consume.
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
There are 3.6 million joules in one kilowatt-hour.

$0.91200 per Kilowatt-Hour (kWh) Yanceyville NC (2006)
Multiply by kilovolts, and you will have it. For example: 1 amp hour X 0.120 kilovolts = 0.120 kilowatt hours
A 40 kilowatt bulb consumes 40 kilowatt-hours of energy in 1 hour. This means it uses 40 kilowatts of power for one hour (40 kW x 1 hour = 40 kWh).
