Doing the Saturday Stumper eh?
It would just be kW. KW stands for kilowatt, and h stands for hour. If you have "kilowatt hour per hour" the hour portion would be divided out.
kWh = Power(kW) x Time (hours)AnswerA kilowatt hour (symbol kW.h) is a unit of measurement of electrical energy.
1 kilowatt means a continuous power flow of 1000 watts, and in one hour the energy expended is 1 kilowatt-hour, also known as 1 kWh or Unit.
Well 1 KWh is "1000 watts per hour". So if you have 400w per hour take400watts per hour divided by 1000 and it shows that you get "0.4KWh".AnswerThere is no such thing as a 'kilowatt per hour', which is why the unit of measurement is a 'kilowatt hour', and NOT a 'kilowatt per hour'!.To determine the number of kilowatt hours of energy consumed by the lamp, multiply its power, expressed in kilowatts, by the length of time it is in use. For your example, the answer is 0.4 kWh.
These do not have the same units. 1 kilowatt hour per meter cubed is in kg m-1 s-2 1 kilojoule per kg is in m2 s-2
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
Kilowatt is a measure of the rate of energy use. It is 1,000 Watts or 1,000 Joules per second. A kilowatt hour is 1,000 Joules per second for 3,600 seconds or 3,600,000 Joules. This means a Kilowatt hour not a rate but a measure of total energy used.
It would just be kW. KW stands for kilowatt, and h stands for hour. If you have "kilowatt hour per hour" the hour portion would be divided out.

We pay for the electricity by the kilowatt hour. An energy-efficient lightbulb has a low kilowatt usage rating.
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.
