3.6 mega joules
1 kwh = 3,600,000 Joules
To convert Joules to kilowatt-hours (kWh), divide the number of Joules by 3,600,000 (the number of Joules in a kWh). For example, to convert 1,000,000 Joules to kWh, you would divide 1,000,000 by 3,600,000 to get approximately 0.278 kWh.
1 kWh = 1,000 watt-hour1 watt = 1 joule per second1 hour = 3,600 seconds(1,000 watt-hour) = (1,000 joule/second) x (3,600 second/hour) = 3,600,000 joules
7.2×106 J. 1 kWh is equal to 3.6×106 J, and 1 J is equal to 2.778×10-7 kWh. 2 kWh is about 1/18 the amount of energy released from the combustion of a gallon of gasoline, and about 1.6 times the amount of energy released by the detonation of one kilogram of TNT. As of November, 2010, that amount of energy would cost about $0.36 to a resident of New York -- up from about $0.26 in 1990.

1 KWh is 1000 joules- hours per second so you change hours to seconds to get; 1 KWh = 1000 x 3600 joules - sec per sec which is 3600000 joules.
1 kWh is a kilowatt-hour, in other words 1000 watts for one hour. That is 1000 Joules per second, for 3600 seconds. So 1 kWh is 3,600,000 Joules, or 3600 kJ.

To convert from energy units (kWh) to joules, you can use the conversion factor: 1 kWh = 3.6 × 10^6 joules. Therefore, 250 kWh is equal to 9 × 10^8 joules.
To convert joules to kilowatts, you need to divide the energy in joules by 3,600,000 (since 1 kWh = 3,600,000 J). Therefore, 4180 J is 0.00116 kWh.
1 kWh = 3,600,000 joules (or watt-seconds).
Energy companies use kilowatt-hours (kWh) instead of joules because kWh is a more convenient and practical unit for measuring the amount of energy consumed by households and businesses. Joules are much smaller units, requiring large numbers for typical energy usage, whereas kWh provides a more manageable figure for billing purposes.
