How many joules in one kilowatt?

Answer 1

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

Answer 2

It 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.

Answer 3

One 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

Answer 4

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

Answer 5

kilowatt is a measurement of power; kilojoule is a measurement of energy

1 kW = 1 kJ/second

Answer 6

watts are power, joules are energy; they don't convert.

However assuming you meant kilowatt hour, which is energy, 3.6 megajoules.

Answer 7

One kilowatt is equal to 1000 joules per second.

Answer 8

1 kWh is equivalent to 3,6.106 joules.

Answer 9

3,600,000 joules.

Answer 10

3 600 000 joules
