1 kilowatt hour = 3,600,000 Joules 1 Tetrajoule = 1,000,000 Joules 1 kilowatt hour = 3.6 Tetrajoules
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.
One joule is equal to 0.00027778 kilowatts when considering the conversion over one second. This is derived from the definition of power, where 1 watt is equal to 1 joule per second. Therefore, to convert joules to kilowatts, you divide by 3,600 (the number of seconds in an hour) to get the kilowatt equivalent.
50 watts is 0.05 kilowatts, so in 24 hours it uses 0.05 x 24 kilowatt-hours, or 1.2 kilowatt-hours of energy.
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.
Use the formula: energy = power x time If energy is in watts and time is in hours, power will be in watt-hours. Divide that by 1000 to get kWh. Alternately, you can convert watt to kilowatt before doing the multiplication - in that case, kilowatt x hours = kilowatt-hours.
The prefix giga means a billion (a thousand millions).

1 kilowatt = 1,000 watts 6 kilowatts = 6,000 watts 6 kilowatt-hours = 6,000 watt-hours
This question has been answered in wikipedia:A joule is ...The work required to continuously produce one watt of power for one second; or one watt second (W·s) (compare kilowatt hour). This relationship can be used to define the watt.http:/en.wikipedia.org/wiki/JouleThe kilowatt hour, or kilowatt-hour, (symbol kW·h, kWh) is a unit of energy equal to 3,600,000 joules. Energy in watt hours is the multiplication of power in watts and time in hours.http:/en.wikipedia.org/wiki/Kilowatt_hour

50 watts is 0.05 kilowatts, so in 24 hours it uses 0.05 x 24 kilowatt-hours, or 1.2 kilowatt-hours of energy.
The average yearly electrical consumption around the world for those areas that have electricity is 3,500 kilowatt hours. In the United States the average is almost 11,000 kilowatt hours.
366,000 BTU = 107.264012 kilowatt hours.
30 minutes is 0.5 hours. 1 kilowatt = 1000 watts, so divide both sides by 1000 and you get .001 kilowatts = 1 watt So 8 watts x 30 minutes = .008 kilowatts x 0.5 hours = .004 kilowatt hours.
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.
Well, I google the convertion table on calculateme.com and I got1 kilowatt hour = 860 420.65 caloriesSo when you have 3 kilowatt hours you get 2579535.6835769564 calories
