Divide the kWh by 1 million
Kilowatthours was created in 1998.
That is impossible. That are different things.

The energy in kilojoule cannot be converted to the power in watts. The time is missing. But you can convert kilojoules to kilowatthours (kWh). Scroll down to related links and look at "Energy Converter".
This would be 30 watthours, or 0.030 kilowatthours
To convert from KVA (kilovoltamperes) to KWH (kilowatthours) first convert to KW (kilowatts) by multiplying by power factor. Power factor is the cosine of the phase angle between voltage and current. Then multiply by the number of hours that you run the load.
energy = power * time = 20w * 1hr = 20 watthours or 0.02 kilowatthours
Your are paying for the work of the electric power company and that is power in kilowatts times time in hours. You pay for "kilowatthours".
The output of nuclear reactors varies with design, but if we take 1000 MWe as typical, and there are 8760 hours in a year, the answer is 1000 x 8760 MegaWatthours, or 8760 GigaWatthours
The output of nuclear reactors varies but if we take 1000 MWe as typical, and there are 8760 hours in a year, this gives 1000 x 8760 MegaWatthours, or 8760 GigaWatthours, or 8.760 TeraWatthours.
kWh stands for kiloWatthours, the amount of electrical energy an appliance uses or generates in one hour measured in kiloWatts. It has nothing to do with one cubic metre of water.
