1. The kilowatt hour (kWh) is a unit of energy.
2. The unit of power is simple the kilowatt (kW).
3. 1 kW = 1 000 W; 33 W = 0,033 kW.
A 10-kilowatt heater produces 34,120 BTUs per hour.
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
That means kilowatt times hour - a power of 1 kilowatt, over a time of 1 hour, would give one kilowatt-hour. It is, therefore, a unit of energy (equal to 3,600,000 joules, since a joule is a watt-second).
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.
There are 1000 kilowatt-hours in a megawatt-hour.
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.
1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules

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 400-watt light uses energy at the rate of 0.4 kilowatt. In 1 hour, it uses 0.4 kilowatt-hour of energy.
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.
1,000 watts
746 watts = 1 horsepower 1,000 watts = 1.3405 horsepower (rounded) 1 kilowatt-hour = 1.3405 horsepower-hour (rounded)
