1 kWh = 3.6 x 106 joules. In engineering notation, that's 3.6E6.

∙ 15y agoIt may be better answered by asking it backwards: "How many Joules are in a kWh?"
1 Joule is 1 Watt-Second. Knowing this, you can derive that 3,600 Joules = 1 watt-hour. 3,600,000 Joules = 1 kilowatt-hour.
To answer your original question, there are 1/3,600,000 kWh in a joule.

∙ 14y agoOne kilowatt is equal to 1 kilojoule per second (1 kW = 1kJ/sec). Therefore if you multiply both by one hour you get 1kw*hr = 1kJ*1hr/sec. Since 1hr = 3600 seconds, the time units cancel out and you are left with 3600. SO, 1 kw*hr = 3600 kJ.
Since you're asking how many kilowatt hours are in 1 kilojoule, we take the reciprocal of that answer. 1kJ = 1 kW*hr/3600 or .000278kW*hrs.
Your answer is .000278

∙ 10y agokilowatt is a measurement of power; kilojoule is a measurement of energy
1 kW = 1 kJ/second

∙ 12y agowatts are power, joules are energy; they don't convert.
However assuming you meant kilowatt hour, which is energy, 3.6 megajoules.

How many watts in 1 kilowatt?
Killo = 1000. There are 1000 watts in 1 kw.
What do you call one thousand watts?
The kilowatt (kW) is one thousand watts.
How many joules are there in a kilowatt-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
How many kw in a kj?
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.
Power is measured in j per what?
Power is measured in Joules per Kilowatt.
One kilowatt equals how many btu per hour?
A BTU is about 1055 joules. A kilowatt is 1000 joules/second, so it is 3,600,000 joules/hour. Dividing that by 1055 joules gives you the equivalent of about 3400 BTU/hour.
How many joules are equivalent to one kilowatt per 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'?
How many watts in 1 kilowatt?
Killo = 1000. There are 1000 watts in 1 kw.
What do you call one thousand watts?
The kilowatt (kW) is one thousand watts.
How many joules are there in a kilowatt-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
Conert 365 kilo watt hours to joules?
365 kilowatt-hours is 1,314,000,000 joules.
How many kw in a kj?
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.
How many joules in a mega joule?
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
How many joules are there in 3kw kettle each second?
Watt means joule/second, kW (kilowatt) means kilojoule/second, i.e., thousands of joules per second.
What does a kilowatt-hour measure?
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.
How do you convert joule to kilowatt-hour?
Joules x 0.000000278 = kW/h
Power is measured in j per what?
Power is measured in Joules per Kilowatt.
