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/Joule
The 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

What does 3.6 MJ mean?
3.6Mj is an amount of energy. The "M" is the metric multiplier for one million (short for Mega) and the "j" means joules, the metric unit of energy named after the physicist "James Prescott Joule". 3.6Mj is therefore 3,600,000 joules of energy. 1 joule is the amount of energy needed to displace a force of 1 newton through a distance of 1 metre. It is also the amount of energy consumed in 1 second at a power level of 1 watt. 3.6Mj will therefore displace a force of 1 newton though 3.6Mm (3600km) or a force of 3.6Mn (3.6 Mega newtons) through a distance of 1 metre.
What is kila joule?
A Joule is a unit of measure for energy. The unit breaks down into N*m (Newton meters). A kJ is 1x10^3J.
How many joules of energy is consumed if the electrical meter shows 400 units of energy?
The electric meter uses kWh (kilowatt x hours) as units; a Joule is a watt x second. Therefore, a kWh has 3.6 million joules. Just multiply by this number.
What is the difference between btus and joules?
1 BTU is the energy required to heat 1 pound of water by 1 degree F. 1 Joule is defined mechanically, but in thermal terms it is 1/4.2 of a calorie (4.2 Joules/calorie), and 1 calorie is the energy required to heat 1 gram of water by 1 degree C. In fact 1 BTU = 1055 Joules.
How much 360000 joules in kilowatt?
"Joule" is an amount of energy. You can hold it in your hand or put it in a jar.If your friend comes along and gives you another joule, then you have twiceas much energy as you had before."Watt" is the rate at which energy moves from place to place. If another friendis coming along and giving you another joule of it every second, then your energyis building up at the rate of one watt."Kilowatt" just means 1,000 watts . . . 1,000 joules every second.So there are a huge number of ways you could collect 360,000 joules of energy.Here are a few ways it could happen:-- 1 watt for 360,000 seconds (100 hours)-- 10 watts for 36,000 seconds (10 hours)-- 100 watts for 3,600 seconds (1 hour)-- 1 kilowatt (1,000 watts) for 360 seconds (6 minutes)-- 10 kilowatts for 36 secondsIn each case, you have 360,000 joules when the time is up.

Convert 600 Joules to MJoules?
One MJ ,Mega Joule, is aqual to 1 million joules. Therefore: 600/1000000= 0.0006J
How many kJ are in a MJ?
About one megajoule. About, because Joule (as an abbreviation) should be spelt with an upper case initial, since it is named after a real person. 1MJ.For a list of all the SI prefixes, (mega, milli,) see the subject under the BIPM website. (Bureau Intenational des Poids et Measures). This is the international agency responsible for these things.
