How many JOULES are in 1 KW.H

Question

i would like to know how many JOULES are in 1 KW.H if 10 KW.H are equal to 360000000 joules. [provide formula]

Using the above: If ENERGY = Power x Time -> Megajoules.. [please tell me how i would work the above out and provide a formula if possible]

thanks

hope it helps!!

Answer 2

Start with the basic conversion of

1 joule/sec =  1 watt

OR

1 joule = 1 watt - sec.

Now, this is where the fun starts. Since

1000 watts = 1 kw and

3600 sec = 1 hour

then

1 joule = 1 watt - sec (1 kw/1000 watts)(1hour/3600 sec)

1 joule = 2.78 x 10^-7 kw-hr.

OR

3.6 x 10^6 joules = 1 kw-hr.

3,600,000 joules = 1 kw-hr.

To get the equivalent of 360,000,000 joules in kw-hr., do the following,

[ 360,000,000/3,600,000 ] = 10

Answer 3

1 kilowatt = 1000 watts (units of power)

                = 1000 Joules per second  (Power = Energy / Time)

      = 1000*3600 (converting seconds to hours, 1hour=3600 secs

= 3.6 x 10^6 Joules or 3600000 Joules in 1 Kilowatt Hour.

Just remember that power is rate of energy transfer, and you can calculate how much energy is transfered(joules) per hour or any other amount of time

Answer 4

It is simply 360,000,000 Joules divided by 10.

3,600,000 is the answer.

I hope this is the answer.
